Abstract

The temperature dependence of the lasing characteristics of InGaAsP/InP distributed feedback injection lasers in the 1. 5 mu m wavelength range is presented. The threshold current density is expressed phenomenologically using the characteristic temperature T//0 of a Fabry-Perot laser and a spectral gain distribution of Gaussian type, which almost agreed with the experimental results in the temperature range of constant T//0. The temperature coefficient of the lasing wavelength was found to be 1. 0 A/K experimentally and calculations taking into account the effect of carrier density could explain this value well. It is also shown that a TM output also appeared in the low-temperature range even if only TE modes were observed at room temperature and at higher temperatures.
