Analog optical computer for AI inference and combinatorial optimization
Experimental set-up The key components of our experimental set-up are shown in Fig. 1a and Extended Data Fig. 1. Optical subsystem The optical subsystem performs matrix–vector multiplication. The basic components are the optical sources (input vector), a system of fan-out optics to project the light onto the modulator matrix and a system of fan-in optics to project the light onto a photodetector array (output vector). The corresponding schematic is shown in Extended Data Fig. 2. The incohere
