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.

摘要: A light absorbing layer composed of intentionally undoped n-type InGaAs and a window layer composed of intentionally undoped n-type InP are formed sequentially on a first principal surface of a semiconductor substrate composed of n-type InP. A cathode is provided on a p-type diffused region forming an island pattern in the window layer, while an anode is provided on a second principal surface of the semiconductor substrate. A side edge portion of the second principal surface of the semiconductor substrate is formed with a gradient portion having an exposed surface with a (112) plane orientation and forming an angle of 35.3° with respect to the second principal surface. The gradient portion is formed to have a mirrored surface by using an etching solution containing hydrochloric acid and nitric acid at a volume ratio of approximately 5:1 to 3:1.

摘要: An optical operational memory device comprises a light-emitting device, a first and second phototransistors, and a load resistor. The light-emitting device and the first phototransistor are connected electrically in series to form an optical bistable switch based on optical positive feedback. The second phototransistor is connected in parallel to the optical bistable switch, and the load resistor is connected in series to the optical bistable switch. The time constant given by the product of the current gain of the second phototransistor, the base-collector capacitance of the second phototransistor, and the resistance of the load resistor is larger than the period required for recombination of the excess majority carriers in the base of the first phototransistor. A single optical beam modulated with pulse signals is input to the first and the second phototransistors simultaneously. The optical pulse with a peak power in a predetermined range turns the optical bistable switch on, and the pulse with higher peak power turns the optical bistable switch off.
