Title:
OPTICAL COMPUTING SYSTEM AND OPTICAL SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/168629
Kind Code:
A1
Abstract:
The present application provides an optical computing system and an optical signal processing method. The digital-to-analog conversion of a high-bit digital signal is completed by means of the cooperation of a plurality of digital-to-analog converters (DACs), so that the whole optical computing system can realize optical operation based on an 8-bit digital signal and a digital signal of 8 bits or more. The optical computing system of the present application comprises: a first DAC, a second DAC and an optical processing unit (OPU), wherein after the first DAC and the second DAC cooperatively receive a digital signal from an electric processor, the first DAC can convert a first effective bit of the digital signal into a first analog signal, and the second DAC can convert a second effective bit of the digital signal into a second analog signal. Then, the OPU can convert the first analog signal into a first optical signal, convert the second analog signal into a second optical signal, and perform operation on the first optical signal and the second optical signal respectively to obtain a third optical signal and a fourth optical signal. Finally, the OPU can amplify and superimpose the third optical signal and the fourth optical signal to obtain a computing result of the digital signal.
