Coherent Homodyne Synaptic Interconnect with Sign- and Weight-Tunable Detection
OFC 2021, virtual event, Jun. 2021, Tu5H.7
We experimentally investigate a synaptic interconnect with low-complexity emitter and coherent receiver. Phase tuning of the LO enables the signed multiplication of the detected signal, which is demonstrated for 130-ps spikes at 1-GHz repetition rate.
