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.
Bassem Tossoun received his BS degree in Computer Engineering and MS degree in Electrical Engineering from Cal Poly San Luis Obispo in 2014. He completed his PhD in Electrical Engineering at the University of Virginia in 2019 with his research interests including silicon photonics and the design, fabrication, and characterization of optoelectronic devices. Currently, he is a Research Scientist at Hewlett Packard Labs working on quantum dot photodiodes and memristor photonics for next-generation supercomputers.
