Smallest Electro-optic modulator is 100 times more energy efficient

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. The new modulator is 10 times smaller and can potentially be 100 times more energy efficient than the best previous

Artificial synapse for neuromorphic chips

Nature Materials – SiGe epitaxial memory for neuromorphic computing with reproducible high performance based on engineered dislocations Although several types of architecture combining memory cells and transistors have been used to demonstrate artificial synaptic arrays, they usually present limited scalability and high power consumption. Transistor-free analog switching devices may overcome these limitations, yet the typical switching process they rely on—formation of filaments in an amorphous medium—is not easily controlled and hence hampers the spatial and temporal reproducibility of the performance. Here, we demonstrate analog resistive switching devices that possess desired characteristics for neuromorphic computing networks with minimal performance variations using
