Suppression of burst-mode operation induced laser wavelength drift for upstream transmission in TWDM-PON by using an integrated heater for thermal control

Abstract

We propose and experimentally demonstrate substantial suppression of the wavelength drift of a 10-Gb/s burst-mode directly-modulated laser for TWDM-PON upstream transmission by using an integrated heater for thermal compensation, reducing the drift by 4.6 times to 5 GHz.
