Filed: 1989-06-14
Abstract: PURPOSE:To detect a change in magnetic flux with a high sensitivity and high S/N by introducing the magnetic flux into the resonator of a laser and utilizing a change in the frequency of the light oscillated by a Zeeman effect. CONSTITUTION:The detector is so formed that the magnetic flux 1 of a magnetic flux density B is applied perpendicularly to the light emission axis of the laser 3 of the semiconductor laser 2. This laser 2 emits the light of the frequency corresponding to an energy level difference as the electrons in atoms transfer from the high energy level to the low energy level. The magnetic field by the magnetic flux 1 introduced into the light emitting part, i.e., the resonator of the laser 2 is cloven and changed in the energy level by the Zeeman effect. The degree of the change in the energy level corresponds to the intensity of the magnetic field. The change in the frequency of the light corresponding to the intensity of the magnetic field is, therefore, obtd. and since this change is sensitive to the magnetic field, the magnetic flux is detected with the high accuracy.

Title: Distributed feedback type semiconductor laser
Inventor: MATSUMOTO KENJI
IPC: H01S5/12
Filed: 1985-07-10
Abstract: PURPOSE:To obtain a semiconductor laser at a stable longitudinal single mode with excellent productivity and with high yield even on modulation at high speed by forming an antiphase corrugation region having a refractive index smaller than an active layer and larger than a waveguide layer between a clad layer and the waveguide layer. CONSTITUTION:The phase of a effective refractive index is displaced at 180 deg. on antiphase corrugations through the phase of the shape of corrugations is the same on the right and left of A-A. In a distributed feedback type semiconductor laser having such effective refractive index distribution, phase is displaced at 90 deg. when laser beams S1 proceeding to the right side from M-M are reflected from a distribution reflector and return in laser beams S1 in a Bragg wavelength determined by a period W and the effective refractive index n0. Likewise, phase is also displaced at 90 deg. in laser oscillation beams S2 proceeding to the left side from A-A. Since A-A and M-M are at W/2 distance at the distance corresponds to the phase of 180 deg., phase is displaced at 360 deg., thus satisfying the conditions of oscillation. Accordingly, the laser is oscillated at a single longitudinal mode at a minimum threshold current value in the same manner as a conventional 1/4 wavelength shift DFB laser.

Abstract: PURPOSE:To prevent the decrease in the effect of current stricture due to minority carrier in an abforption layer by a method wherein a current block layer of the same conductivity type as that of a substrate is provided between the photo absorption layer and a clad layer of a conductivity type different from that of the substrate. CONSTITUTION:The N-clad layer 1mum 2, an undoped active layer 0.07mum 3, the P- clad layer 0.25mum 4, the N-current block layer 0.1-0.2mum 5, and the N-photo absorption layer 0.4mum 6 are successively crystal-grown. Next, etching is carried out down to the layer 5 to a stripe form of a width 2mum, and a P-layer 1mum 7 and a P-cap layer 0.5mum 8 are crystal-grown thereon.
