Neuromorphic photonic computing with an electro-optic analog memory
Nature CommunicationsAbstract In neuromorphic photonic systems, device operations are typically governed by analog signals, necessitating digital-to-analog converters (DAC) and analog-to-digital converters (ADC). However, data movement between memory and these converters in conventional von Neumann architectures incur significant energy costs.
