Abstract
In this paper, a new method for flat sweeping automatic hold of wavelength swept laser has proposed. Through the performance test on the implemented laser, even 5 hours passed, the flat sweeping has held up well, and 56nm flat sweeping range, 1kHz sweeping frequency, and 8.8mW average optical power were obtained. This showes that the proposed can eliminate the necessity of hand-operated polarization control required for previous swept lasers in case of long time operation and also optical spectrum analyzer needed to monitor the sweeping spectrum status.
