Abstract
A method for controlling an electromagnetic radiation source to produce single mode operation having an optimized side-mode suppression ratio over a set of wavelengths within a prescribed temporal profile. The electromagnetic radiation source is configured to output electromagnetic radiation at a given wavelength based upon parameters. The method includes determining a set of parameter combinations that satisfy a condition for a desired set of wavelengths and a minimum side mode suppression ratio over the range of wavelengths. The set of parameter combinations define sub-paths for nearly arbitrary transitions from one wavelength to another wavelength. Combinations of select sub-paths provide a multivariate path for transitioning over the range of wavelengths. The method also includes controlling the semiconductor laser to emit electromagnetic radiation over the range of wavelengths by traversing the multivariate path in a desired manner.
