Hybrid III/V-on-Si memristive optoelectronic devices for integrated photonic neuromorphic computing

We present memristor integrated microring modulators and lasers with non-volatile memory on a silicon photonic platform. III-V and Si substrates are bonded together and sandwich a thin oxide layer which forms a memristor. By changing the state of the memristor, the operating wavelength of microring lasers and modulators can be tuned in a non-volatile fashion. In this unique platform, we can integrate configurable, linear synaptic weights in the form of the resistance levels of memristors directly on the same chip as non-linear active optoelectronic devices, such as III-V lasers and modulators, to produce an integrated photonic neuron.
