    Abstract: A method for sweeping an electromagnetic radiation source (12) to produce single mode operation having an optimized side-mode suppression ratio over a continuous range 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 maximum side mode suppression ratio over the range of wavelengths. The set of parameter combinations define sub-paths for transitioning 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.

    Abstract: A method is described for qualifying a multisection semiconductor laser (100) using measurements of excursions from stable operating conditions (61) to neighbouring mode boundaries (52, 142) at which the laser undergoes mode-hopping. These excursions are measured when the laser is characterised to provide a measure of the stability and hence the quality of the laser, and to facilitate statisctical analysis of the quality of a batch of lasers from a given wafer. The values of the excursions may be re-measured during the life of the laser using a curtailed version of the characterising procedure rapidly to monitor aging or other deterioration of the laser (100).

    Abstract: Controller calibration methods for use with sampled grating distributed Bragg reflector SGDBR laser (102) is presented. An exemplary method includes conducting a two-dimensional mirror current scam of each front mirror current setting and back mirror current setting for a sampled grating distributed Bragg reflector SGBDR laser(102) to produce laser setting data corresponding to each front mirror current setting and back mirror current setting to generate a reference optical signal (114) of the SGDBR laser (102). A channel operating point is determined for each channel within thetwo-dimensional scan data. A fix up of the operating point to substantially minimize wavelength and power error can also be perfo rmed. A two-dimensional control surface is characterized at the channel operating point for each channel. A lookup table for controlling the SGDBR (102) laser is generated from the operating point currents, locker values and two-dimensional control surface data from each channel.
