英文摘要 | A semiconductor light-emitting unit includes: a semiconductor laser diode; a photodetector functioning as a sub-mount for mounting the diode thereon; and a heating member, incorporated with the photodetector, for heating the diode. If the ambient temperature of the diode falls within a range where kinks are possibly caused in the low-temperature I-L characteristic of the diode, then current is supplied to the heating member, thereby heating the diode. The heating member may be either a doped region defined within a semiconductor substrate or a doped polysilicon film formed on the substrate. Also, the heating member is preferably located under the laser diode with a heat-dissipating layer and an insulating layer interposed therebetween. The semiconductor light-emitting unit with this structure can effectively eliminate kinks from the low-temperature I-L characteristic of the semiconductor laser diode. |
