The temperature dependence of the lasing characteristics of InGaAsP/InP distributed feedback injection lasers in the 1.5 Ɓm wavelength range is presented. The threshold current density is expressed phenomenologically using the characteristic temperature T0of 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 T0. The temperature coefficient of the lasing wavelength was found to be 1.0 Ɨ/K experimentally and calculations taking into account the effect of carrier density could explain this value well. It was 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.
