Abstract :
A TDA-CSG DR laser with a narrow linewidth of 300 kHz has been controlled to lock on 6.25 GHz resolution flexible grid using two compact 50 GHz-FSR Fably-Perot etalon filters. Fast wavelength switching time of less than 1 msec including feedback control time is also ensured for whole C-band wavelength range.
