Stanford photonic chip transmits data 100x faster, cuts power use 90%

Stanford University researchers have built a photonic chip the size of a thumbnail that transmits data 100 times faster than conventional silicon chips while cutting power consumption by 90 percent, according to findings published by the Stanford Engineering team in May 2026.

How it works

The chip routes data using light pulses through etched waveguides rather than electrical signals — a photonic integrated circuit (PIC) design. This eliminates heat and resistance losses that throttle copper-based interconnects inside servers and fibre routers.

Conventional data-centre interconnects consume 30–40 percent of a facility’s total power budget, per the International Energy Agency’s 2024 Data Centres and Transmission Networks report. A 90 percent cut in that load would substantially reduce operating costs for hyperscale operators worldwide.

India’s data centre bill

India’s data-centre capacity is expanding fast. The Ministry of Electronics and Information Technology (MeitY) targets 1,000 megawatts of commissioned capacity by end-2026 under the Data Centre Policy 2020. Power is the largest operating cost, running at ₹6–8 per unit across most states.

A 90 percent reduction in interconnect power draw could cut per-rack energy bills by an estimated ₹1.2 lakh annually at current Delhi NCR tariffs. Operators including NTT India, CtrlS, and STT GDC have lobbied state governments for cheaper renewable procurement to address exactly this cost pressure.

The speed gain matters equally for BharatNet Phase III, which targets 6.4 lakh villages with high-speed fibre by December 2026. Faster optical routing at aggregation nodes could raise effective throughput without laying additional fibre, lowering the programme’s per-village cost.

MEA did not respond by publication time to a request for comment on whether the Department of Telecommunications plans to engage Stanford on technology transfer or licensing.

When it reaches market

Stanford’s team has not named a commercial partner. Analysts at Omdia estimate photonic chips could enter hyperscale procurement cycles by 2028 at the earliest, given packaging and manufacturing scale-up requirements. Rival programmes at MIT and imec Belgium are targeting the same window. India’s IIT Madras photonics lab, operating under the Semicon India programme, works on related integrated-optics research but is not a named co-researcher on this project.
