The temperature dependence of the lasing characteristics of InGaAsP/InP distributed feedback injection lasers in the 1.5 μm 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 wavelenuth was found to be 1.0 Å/K exrerimentally and calculations taking into account the effect of carrier density could explatn thns 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.
