Figure 2. Ultra-high parallel optical computing architecture. a Systematic scheme comprising three key components: (1) microcomb-based spectral encoder for parallel vector input and wavelength division multiplexing (WDM) (2) broadband Mach-Zehnder interferometer (MZI) mesh network implementing wavelength-parallel multiply-accumulate (MAC) operations and (3) demultiplexed output channels with wavelength-independent detection. DEMUX: demultiplexer, MUX: multiplexer b Schematic of 100-channel wavelength-parallel optical computing. A Kerr microcomb produces over 100 phase-locked carriers across the telecommunication band. Individual comb lines are modulated via parallel electro-optic interfaces for vector encoding. The wavelength-multiplexed signal propagates through a reconfigurable MZI mesh. Programmable voltage drivers enable high-accuracy dynamic weighting of photonic MAC units.
