For emerging TWDM-PON systems, based on burst-mode operation over WDM channels, a main challenge is the laser self-heating during bursts. This effect creates a drift of the emission frequency, leading to degraded transmission performances, and perturbation of adjacent channels. We explain an accurate method for characterization of wavelength drift during ...
