Abstract: Examples of the present technology provide “tensorized” integrated coherent Ising machines that improve scalability by leveraging a tensorized optical coupling matrix comprising layers of multi-wavelength photonic tensor-train (TT) cores cascaded together via passive optical cross-connects. A multi-wavelength photonic TT core may comprise a Mach Zehnder interferometer (MZI) mesh (i.e., a lattice/array of interconnected MZIs) that modulates the phase and/or amplitude of optical signals. Tensorized integrated CIMs of the present technology can achieve further scalability optimizations by implementing bistable Ising nodes via one or more multi-wavelength Ising node collections. A multi-wavelength Ising node collection may comprise a bistable Ising nodes implemented on a common MZI, where each bistable Ising node of the multi-wavelength Ising node collection is associated with a separate wavelength of light.

Abstract: Systems and methods are provided for general matrix multiplication using wavelength parallel processing of a photonic tensor core. Examples of the systems and methods disclosed herein include encoding a second matrix into a plurality of optical signals based on a plurality of free spectral ranges (FSRs) of an array of resonator structures, the resonator structures having resonances tuned based on a first matrix. The optical signals can be input into input waveguides optically coupled to the array of resonator structures. A third matrix, representative of the first matrix multiplied by the second matrix, can be generated based on optical power output from the array of resonator structures.
