Abstract
The spectral characteristics of a semiconductor laser are altered by i njecting additional noise current into its current-drive port. A conti nuously varying spectral linewidth from about 5 MHz to above 100 MHz i s achieved experimentally in this semiconductor laser. The conditions under which the line shape changes from a standard Lorentzian shape to a Gaussian shape as functions of laser power and noise current are in vestigated and compared with an existing theoretical treatment.
