Reconfigurable Photonic Integrated Circuit for All-Optical Matrix Inversion
摘要
We report on the design and experimental validation of a programmable silicon photonic architecture solving recursive mathematical problems directly in the optical domain. The reconfigurable kernel of the circuit is realized through a mesh of thermally tuneable Mach-Zehnder Interferometers, which is embedded into optical feedback loops and is used to implement arbitrary unitary matrices. The proposed architecture is employed to experimentally demonstrate matrix inversion without any optical-to-electrical conversion.
