Optical synaptic devices with ultra-low power consumption for neuromorphic computing.

ABSTRACT: Brain-inspired neuromorphic computing, featured by parallel computing, is considered as one of the most energy-efficient and time-saving architectures for massive data computing. However, photonic synapse, one of the key components, is still suffering high power consumption, potentially limiting its applications in artificial neural system. In this study, we present a BP/CdS heterostructure-based artificial photonic synapse with ultra-low power consumption. The device shows remarkable negative light response with maximum responsivity up to 4.1 × 10⁸ A W^-1 at V_D = 0.5 V and light power intensity of 0.16 μW cm^-2 (1.78 × 10⁸ A W^-1 on average), which further enables artificial synaptic applications with average power consumption
