Abstract :
Static and dynamic thermal processes are incorporated into the modelling and simulation of the three-electrode distributed Bragg reflector (DBR) lasers. An analysis of thermal contribution to bandwidth increase and linewidth decrease in multielectrode DBR lasers is presented. It is theoretically shown that the position of the lasing mode relative to the Bragg reflection peak is influenced by thermal effects, so that if the lasing mode is biased at the long wavelength side of the Bragg reflection peak, a significant increase in 3 dB modulation bandwidth and decrease in spectral linewidth can be obtained
