Wavelength and temperature changes will cause functional failures for silicon photonic filters. Here we experimentally demonstrate automatic work wavelength alignment (function maintaining) for silicon AMZI filters against large variations in external wavelength and temperature by implementing reinforced Q-learning algorithm in microcontroller of only 8-KB memory.
