摘要： A semiconductor light source includes a light-emitting device 101 having a plurality of semiconductor layers made of nitride semiconductors, and a drive circuit 102 for driving the light-emitting device 101. The drive circuit 102 performs forward drive operation, in which a forward current is supplied to the light-emitting device to make the light-emitting device 101 emit light, and reverse drive operation, in which a reverse bias is applied to the light-emitting device. The magnitude of the reverse bias is limited by the value of a reverse current flowing through the light-emitting device.

摘要： A semiconductor laser (101) includes a first cladding layer (103), an active layer (105) and a second cladding layer (108). A window region (115) including fluorine, that is, an impurity element with higher electronegativity than nitrogen, is formed in the vicinity of a front end face (113) and a rear end face (114) of a laser resonator. The window region (115) is formed by exposing the front end face (113) and the rear end face (114) to carbon fluoride (CF4) plasma. The effective band gap of a portion of the active layer (105) disposed in the window region (115) is larger than the effective band gap of another portion of the active layer, and hence, it functions as an end face window structure for suppressing COD.
