Light Rays Can Replace Copper Circuits for Future Computers -Intel

Intel Corporation has announced an important advance in the quest to use light beams to replace the use of electrons to carry data in and around computers. The company has developed a research prototype representing the world’s first silicon-based optical data connection with integrated lasers. The link can move data over longer distances and many times faster than today’s copper technology; up to 50 gigabits of data per second. This is the equivalent of an entire HD movie being transmitted each second.
Today computer components are connected to each other using copper cables or traces on circuit boards. Due to the electro-magnetic interference that comes with using metals such as copper to transmit data, these traces have a limited maximum length. This limits the design of computers, forcing processors, memory and other components to be placed just inches from each other. Today’s research achievement is another step toward replacing these connections with extremely thin and light optical fibres that can transfer much more data over far longer distances, radically changing the way computers of the future are designed and altering the way the data centre of tomorrow is architected.
For example, tomorrow’s datacenter or supercomputer may see components spread throughout a building or even an entire campus, communicating with each other at high speed, as opposed to being confined by heavy copper cables with limited capacity and reach. This will allow datacenter users, such as a search engine company, cloud computing provider or financial datacenter, to increase performance, capabilities and save significant costs in space and energy, or help scientists build more powerful supercomputers to solve the world’s biggest problems.
Justin Rattner, Intel chief technology officer and director of Intel Labs, demonstrated the Silicon Photonics Link at the Integrated Photonics Research conference in Monterey, California. The 50Gbps link is akin to a “concept vehicle” that allows Intel researchers to test new ideas and continue the company’s quest to develop technologies that transmit data using light rays with low cost and easy to make silicon. While telecommunications and other applications already use lasers to transmit information, current technologies are too expensive and bulky to be used for PC applications.
 “This achievement of the world’s first 50Gbps silicon photonics link with integrated hybrid silicon lasers marks a significant achievement in our long term vision of ‘siliconizing’  photonics and bringing high bandwidth, low cost optical communications in and around future PCs and servers” Rattner said.
The 50Gbps Silicon Photonics Link prototype is the result of a multi-year silicon photonics research agenda, which included numerous “world firsts.” It is composed of a silicon transmitter and a receiver chip, each integrating all the necessary building blocks from previous Intel breakthroughs including the first Hybrid Silicon Laser co-developed with the University of California at Santa Barbara in 2006 as well as high-speed optical modulators and photo-detectors announced in 2007.
The transmitter chip is composed of four such lasers, whose light beams each travel into an optical modulator that encodes data onto them at 12.5Gbps. The four beams are then combined and output to a single optical fibre for a total data rate of 50Gbps. At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors, which convert data back into electrical signals. Both chips are assembled using low-cost manufacturing techniques familiar to the PC industry. Intel researchers are already working to increase the data rate by scaling the modulator speed as well as increase the number of lasers per chip, providing a path to future terabit/s optical links – rates fast enough to transfer a copy of the entire contents of a typical laptop in one second.
This research is separate from Intel’s Light Peak technology, an effort to bring a multi-protocol 10Gbps optical connection to Intel client platforms for nearer-term applications. Silicon Photonics is a research effort aimed at using silicon integration to reach tera-scale I/O bandwidths, which could be applied to a variety of future applications over time. Both are components of Intel’s overall I/O strategy.
Intel Corporation is a world leader in computing innovation. The company designs and builds the essential technologies that serve as the foundation for the world’s computing devices.

Meta, a multinational technology company, has informed advertisers that it will begin applying new location-based fees to certain advertisements delivered in six selected jurisdictions starting July 1, 2026, as the company moves to offset costs linked to digital services taxes and other regulatory charges.

Meta to Charge Location Fees on Ads to Six Countries from July 1, 2026

In an email sent to advertisers, the company explained that the new charges will apply to ad impressions delivered to audiences in specific countries, regardless of where the advertiser’s business is based.

“Meta will soon apply new location fees to ads delivered in specific jurisdictions to cover digital service taxes (DST) and other location-based fees imposed on Meta in those jurisdictions,” the company said in the mail.

According to the notice, the fees will be applied to ads delivered in Austria (5%), France (3%), Italy (3%), Spain (3%), Türkiye (5%), and the United Kingdom (2%).

The company added that these rates and jurisdictions could change over time.

Meta described location fees as additional charges tied to where ads are delivered rather than where the advertiser operates.

“Location fees are additional charges that may apply to ads delivered in selected jurisdictions to cover part of the costs associated with doing business in those jurisdictions,” the company said.

The company noted that the charges will be calculated after ads are delivered and will not be deducted from campaign budgets.

Meta gave an example in the email: if an advertiser spends $100 on ads delivered in Italy, where the location fee is 3%, the final cost would be $103, excluding any applicable value-added tax.

Explaining the reason for the change, the company pointed to regulatory developments affecting technology platforms.

“The cost of delivering ads in specific jurisdictions is changing due to the evolving regulatory landscape, including digital services tax legislation. Until now, Meta has covered these additional costs,” the company said.

The company added that the move aligns with broader industry practices, noting that other digital platforms may introduce similar charges linked to digital service taxes.

Meta said the location fees will apply to all ad formats, including image and video ads, as well as campaigns such as WhatsApp click-to-message ads that are billed together with advertising.

The fees will appear on invoices with clear descriptions by jurisdiction, such as “Italy digital services,” the company said, adding that taxes like VAT will still be applied on top of the total amount.

Advertisers were advised to review the affected ad accounts and share the update with their finance, procurement and marketing teams to prepare for the changes.

Tizeti Network Limited, West African broadband provider, has launched an advertising-supported internet platform across its hotspot network in Nigeria and Ghana, allowing users to watch short video adverts in exchange for data access.

Tizeti Tests Ad-Funded Internet Access Model in Nigeria and Ghana

The system converts advertising engagement into internet connectivity, offering users the option to view a short video advertisement to unlock data without paying upfront.

Tizeti said the platform is now active across all its hotspot locations in the two countries, covering residential areas, campuses, commercial districts and other high-traffic urban locations.

The service runs on Google Ad Manager’s rewarded web advertising technology, which allows users to voluntarily watch advertisements and receive data rewards once the video is completed.

At a hotspot location, users connect to the network as usual but are given the option to watch a short advert in exchange for a defined amount of data. Those who choose to participate can repeat the process to earn additional internet access.

The company said the approach creates a value exchange between users, advertisers and network providers.

Users gain internet access without immediate payment, while advertisers reach audiences who have actively chosen to view their messages.

“Internet access is a fundamental driver of opportunity,” said Nsikak Asuquo, West Africa manager at Tizeti Network Limited.

“By rolling out reward-based internet access across Nigeria and Ghana, we are expanding connectivity without financial barriers while offering brands a high-engagement platform to reach more than 2.5 million active users,” he added.

Tizeti said participation in the advertising programme is voluntary and operates under its privacy policies, with data handled in compliance with the Nigeria Data Protection Act and Ghana’s Data Protection Act.

The launch comes as Africa’s digital advertising market expands rapidly. Industry projections suggest programmatic advertising spending could exceed $5 billion on the continent by 2028 as brands increasingly shift marketing budgets online.

By integrating Google’s advertising infrastructure directly into its hotspot network, Tizeti aims to turn public Wi-Fi locations into scalable digital advertising channels while widening access to the internet.

Advertisers will be able to buy ad placements through Google Ad Manager’s ecosystem, including open auctions, private deals and programmatic guaranteed campaigns.

Tizeti said its hotspot network serves more than 2.5 million active users across Nigeria and Ghana.

The company provides broadband services using a mix of fibre infrastructure and public Wi-Fi networks, targeting communities, schools and businesses across the region.
