Reinforced Q-Learning Enabled Automatic Blind Working Wavelength Alignment Against Wide Input-Wavelength Shifts and Temperature Variations for Silicon Photonic Vernier Ring Filters

Abstract

We experimentally demonstrate long-time (~10 hours) continuous full-C-band automatic working wavelength alignment for silicon photonic cascaded-ring vernier filters against wide input-wavelength and temperature changes using reinforced Q-learning method, without pre-building look-up table and temperature monitor.
