Abstract

We demonstrate a new and robust digital method to remotely track rapid (1 C/min) uncontrolled environmental changes in a WDM device. Our method requires no RF circuitry, wavelength standard, or analog dithering. Our method enables a multiwavelength source to track a multi-channel WDM component in the field within a local loop environment which is characterized by large temperature and received power variations, hardware limitations, and power fluctuations.
