World's smallest electro-optic modulator

30.11.-0001 | Oregon State University | oregonstate.edu

Researchers at Oregon State University have designed and fabricated the world’s smallest electro-optic modulator, which could mean major reductions in energy used by data centers and supercomputers.

An electro-optic modulator plays the key role in fiber optic networks. Just as a transistor is a switch for electronic signals, an electro-optic modulator is a switch for optical signals. Optical communication uses light, so the modulator turns on and off the light that sends a stream of binary signals over optical fibers.

Electro-optical modulator

The new modulator is 10 times smaller and can potentially be 100 times more energy efficient than the best previous devices. It is roughly the size of a bacterium, measuring 0.6 by 8 microns.
