Title: Semiconductor laser
Inventor: TOMITA AKIHISA
IPC: H01S5/343
Filed: 1996-03-21
Abstract: PROBLEM TO BE SOLVED: To obtain a red-light semiconductor laser having a low threshold value, by turning a quantum well construction comprising a barrier layer of a lattice constant smaller than the lattice constant of a substrate and a well layer with a lattice constant larger than the lattice constant of the substrate into an active layer, thereby realizing a strained quantum well construction having a good containment of electrons. SOLUTION: By using a substrate 11, located between 0.565nm and 0.56nm of lattice constant, a GaInP mixed crystal having a lattice constant larger than the lattice constant of the substrate 11 is set as a well layer 14, and a quantum well construction using AlGaInP mixed crystal having a lattice constant smaller than lattice constant of the substrate 11 as a barrier layer 142 is set as an active layer 14. By doing this, the band gap increases. Therefore, the well width of a compressed strained quantum well can be made almost 5nm, by which a degradation in characteristics due to the dispersion of the well layer 141 during growth can be avoided. Also, sufficient containment can be expected. Moreover, leakage of electrons through X point in a clad layer 16 can be suppressed.

IPC: G11B7/135
Filed: 1989-03-16
Abstract: PURPOSE:To constitute this device so that no jitter is generated in data and no unreadable recording defect is generated even if a wavelength fluctuation is generated in a semiconductor laser at the time of recording by allowing the direction for enlarging the beam diameter by a beam shaping prism to become orthogonal to the direction of a recording data train on an optical disk medium.

That is, at the time of wavelength fluctuation of a semiconductor laser 1 generated at the time of recording, etc., a convergent point B is generated in parallel to the same direction as the beam enlargement direction against a convergent point A, but by allowing the direction of displacement to the convergent point B from this convergent point A to become orthogonal to the direction of the recording data train 101, a recording data interval fluctuation caused by a wavelength fluctuation generated at the time of recording is not generated, and an unreadable recording defect caused by the generation of a data jitter is not generated.

Abstract: PROBLEM TO BE SOLVED: To simplify control by controlling the phase of signal light by selecting one or more electrodes and applying voltage. SOLUTION: Electrodes 41a to 41c are provided on an optical waveguide 4a as electrodes for applying voltage to respective waveguides 4a to 4g. Similarly, electrodes 42a to 42c are provided on the optical waveguide 4b. When all the electrodes 41a to 41c are not applied with voltage signal light does not shift in phase at all and reaches a star coupler 3b. As the number of electrodes applying voltage increases, the phase shift quantity that the signal light has increases. The optical waveguides 5a to 5d are arranged at positions corresponding to the phase shift quantities and then the output destination of the signal light can be selected by selecting the electrodes 4a to 4c for applying the voltage. As for the optical waveguides 4b to 4g, signal light shifts in phase by selecting electrodes 42a to 42c... 47a to 47c for applying voltage.
