Electronic/photonic chip sandwich pushes boundaries of computing and data transmission efficiency

https://techxplore.com/news/2022-11-electronicphotonic-chip-sandwich-boundaries-transmission.html

"The resulting optimized interface between the two chips allows them to transmit 100 gigabits of data per second while producing just 2.4 pico-Joules per transmitted bit. This improves the electro-optical power efficiency of the transmission by a factor of 3.6 compared to the current state-of-the-art. A picojoule is one-trillionth of a Joule, which is defined as the energy released in one second by a current of 1 ampere through a resistance of 1 ohm—or about 0.24 calories"
