Abstract

The influence of longitudinal mode spatial hole burning (LMSHB) on the performance of DFB laser structures is examined in detail. A comprehensive model has been used to interpret the experimental results and construct a theoretical framework that has been utilized to develop more advanced device designs. An increasing side mode intensity with output power, movement of the lasing mode relative to the stop band, and curvature of the light-current characteristic at low power can all be manifestations of the influence of LMSHB on the static device performance. The dynamic behavior can also be affected, with extended wavelength chirp and amplitude patterning effects on the timescale of the effective carrier recombination time being particularly important.
