A Novel Working Scheme for Robust Optical Coupler Unit for Programable Unitary Matrices
Programmable optical unitary matrices (POUMs) in photonic integrated circuits (PICs) technology play a critical role in modern information technology. With the expansion of their scale and integration density, POUMs have their performance limited by fabrication errors and tuning phase errors of thei...
