Claim:
1. A method for operating a semiconductor laser, including a laser optical waveguide formed on a substrate and a reflector at a first end region of the laser optical waveguide, to generate a continuous-wave laser output optical signal, the method comprising: (a) applying a substantially constant first electrical laser drive current I (b) applying a substantially constant second electrical laser drive current I (c) applying a time-varying wavelength-dithering current to the first electrode, wherein: (d) the laser output optical signal is emitted from a laser optical signal output at a second end region of the laser optical waveguide and is characterized by a laser output optical power level and a laser optical signal wavelength; (e) applying the laser-dithering current results in spectral broadening of the laser output optical signal; and (f) I
