Abstract
Methods of controlling semiconductor lasers are provided where, the time-averaged optical spectrum of the semiconductor laser is broadened by modulating the drive current at a relatively high frequency. Generally, the frequency of the drive current modulation is high enough to induce wavelength chirping within the data periods encoded in the gain current signal. Laser controllers and projections systems operating according to the disclosed methodology are also provided.
