Abstract
This paper presents a novel method for wavelength-continuous tuning of a MG-Y-Branch Laser that possesses an intrinsic self-calibration capability. The method utilizes the measured characteristic output power pattern caused by the internal longitudinal cavity modes of the laser device to calibrate a set of cubical spline curves. The spline curves are then used to generate the tuning currents for the two reflector sections and the phase section of the laser from an intermediate tuning control parameter. A calibration function maps the desired laser wavelength to the intermediate tuning parameter, thus enabling continuous tuning with high accuracy.
