Phase-Drift Limits and Adaptive Quadrature Readout in Programmable Photonic Processors
Gökhan Elmas, Igor A. Litvin, Janis Nötzel
Phase fluctuations between optical inputs limit programmable photonic processors because their output powers depend on coherent interference. We study the phase-drift penalty that…

Local Variance-Based Calibration of Programmable Photonic Interferometer Meshes
Gökhan Elmas, Igor A. Litvin, Janis Nötzel
Programmable photonic interferometer meshes enable reconfigurable linear optical transformations, but their performance depends critically on accurate calibration of Mach-Zehnder i…
