Title: Current supply source and semiconductor laser drive circuit
Inventor: UNO HITOSHI
IPC: G05F3/20
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To provide a current supply source which produces a current value having a large change rate to temperature or having an increased change rate to temperature, when the temperature exceeds a threshold value, and also to provide a semiconductor laser drive circuit which has less fluctuation in its optical output power over a wide range of temperatures. SOLUTION: A laser driving current supply source 4 for driving a semiconductor laser 1 includes two voltage-controlled current supply sources 41 and 42 and a control voltage generation source 43. The voltage generation source 43 outputs control voltages to the two voltage-controlled current supply sources 41 and 42, in such a manner that the current source linearly changes its current value to a temperature to turn off the current source 42 when the temperature is lower than a threshold value, and to linearly change the current value when the temperature is higher than the threshold. As a result, temperature characteristics of the semiconductor laser can be compensated for in a wide range of temperatures, and thus there can be realized a semiconductor laser drive circuit which can produce a less-fluctuated optical output power.

Title: Semiconductor laser
Inventor: MATSUI TERUHITO
IPC: H01S5/00
Filed: 1986-07-25
Abstract: PURPOSE:To shorten the emitting light wavelength of a semiconductor laser by providing a light absorbing region in an optical waveguide of the laser to increase a resonator loss. CONSTITUTION:A P-type AlGaAs layer 5 and an N-type AlGaAs layer 3 to become clad layers are provided on and under a GaAs quantum well active layer 4, have forbidden band width larger than that of the layer 4, and smaller refractive index than that. Thus, a resonator is enclosed, and a light is enclosed, and the light is amplified to be oscillated between the reflecting end faces 8 of the resonator. The laser is recombined at carrier in the part of a P-type electrode 7 to provide a gain, but an optical waveguide under the part having no electrode becomes an optical absorption region 9 to increase its loss alphaac. The value of alpha is increased due to the loss to increase the resonator loss. That is, the same material can oscillate in a shorter wavelength.

Abstract: PURPOSE:To correct an error in time of reflection produced by a change in sonic velocity due to temperature by changing the driving signals of an ultrasonic oscillator in response to the temperature characteristics of the resonant frequency of the oscillator and making the driving signals clock pulses for measuring the time of reflection. CONSTITUTION:A distance or the presence or absence of an object is detected by measuring time of reflection from the transmission of an ultrasonic wave to the return of the reflected wave or transmitted wave.
