Thermal contribution to the side-tuning of the lasing mode in multielectrode DBR lasers: influence on modulation bandwidth and laser linewidth

Abstract

Stationary temperature distributions in the three-electrode DBR lasers are calculated analytically using Fourier transforms. It is theoretically shown 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.
