Electric field is applied to an electrostriction element by means of an electrostriction element driver 5 and, when its shape is changed, the electrostriction element approaches the total reflection surfaces 1a of the corner cubes 1A, 1B. Thus, the reflectivity is changed.

When the intensity modulated transmission light beam (P polarization) and the reflection light beam (S polarization) are combined on the branching/combining surface 2d. polarization modulation is performed as a result.

A linearly polarized laser beam enters the prism, and the beam is split into two polarized components, the intensities of which vary with roll orientation of the detector relative to the polarized laser beam. The outputs of the two photodetectors are connected to the positive and negative inputs, respectively, of a high gain differential amplifier which provides a roll output. | ||||||
| 13 | Semiconductor laser beam branching device | JP10810878 | 1978-09-05 | JPS5535354A | 1980-03-12 | SASAKI MASARU |
| PURPOSE: To branch the laser beam accurately, by using a modified Glan-Thompson prism, in an optical fiber type signal optical transmission system using semiconductor laser beam. CONSTITUTION: A modified Glan-Thompson prism 9 is combined with a branching prism 10, which are disposed in an optical path. A light 2 from a laser 1 reaches a boundary surface l of 9, and a normal beam 24 is reflected, while an abnormal beam 23 advances straightly. The abnormal beam 23 is directed towards prism surfaces m, m' which are flat mirror surfaces. When the distance between m and m' is several timers longer than the wavelength of light 2, the beam 23 is totally reflected by the surface m, and is emitted only to the direction of optical fiber 8. But, if the distance between m and m' is shorter than the wavelength of light 2, part of beam 23 passes through the surface m' due to ooze out effect (tunnel effect),and is emitted to an optical fiber 7. By varying the pressure F applied through a supporting part 11 of the prism 10, the distance between m and m' may be changed, so that the light branching rate to the optical fibers 7, 8 may be controlled.

| PURPOSE:To obtain the detecing sensitivity close to a theoretical limit, by moving the position of a half mirror by an electric distorting element, imparting phase difference to incident light rays at both ends of an optical fiber coil, measuring the phase difference only when the light combined by the half mirror is transduced into an electric signal, thereby weakening the effect of noises.

One of the split light passes a spherical lens 21b, becomes the light CCW in the counter clockwise direction through a constantly polarizing fiber 15, and returns to the lens 21a. The other is relfected by the mirror 23 and becomes the light CCW in the counterclockwise direction in the constantly polarizing fiber 15. The phases of both signals are shifted through a phase plate 16. The signals are detected by a light detector 17 and outputted through a phase detector 18. | ||||||

| PURPOSE:To detect position deviation in two directions by using a diffraction grating wherein grating lines are arranged in the oblique direction. CONSTITUTION:A Zeeman laser light source 30 outputs two luminous fluxes having different frequencies. The outputted light is branched in two paths according to polarization directions by a polarization beam splitter 31. The branched beams pass a mirror 32 and a mirror 34, respectively, and illuminate a linear diffraction grating 35 formed on a mask 34 and a linear diffraction grating 37 formed on a wafer 36. Grating lines are arranged in the oblique directions to constitute the above gratings 35, 37. Diffracted lights from them pass mirrors 38, 39 and are collected in a beam splitter 40. Further said lights pass a Glan- Thompson prism 41, and are made to enter a photo detectors 43 and 44, respectively, by an edge mirror 12, according to the polarization directions. Thus the respective light beat signals are obtained. Said light beat signals are inputted in a phase-meter 45, and the deviation of the diffraction gratings 35, 37 is detected from the phase difference. | ||||||

| PURPOSE: To improve the manufacturing yield of a collimator laser diode by rotating a laser element by a rotating mechanism to introduce a maximum light power incident to a fiber to accurately set a polarized surface to a specified position. CONSTITUTION: In order to assemble a collimator laser element, a guide pin 11 is matched to a cutout 12 of a cap 10, the cap 10 is fixed to a V-shaped groove holder 15, and the cap 10 is regulated by engaging the guide pin of a chuck with a hole formed at a stem 31. Then, a laser beam is output from a laser chip 21 by a laser diode driver 21. The beam is input through a lens 18 and a Glan-Thompson prism 17 to an optical fiber 16, and then measured by a power meter 22. If the power is smaller than a specified value, it exhibits that the polarized surface of the beam is not aligned. Accordingly, a rotating mechanism 20 is turned ON to regulate the cap 10, and when a predetermined power is obtained, the cap 10 is secured, for example, by a solder 33 to the stem 31.

| PURPOSE:To obtain high detection sensitivity by making the direction of a polarized wave input to an optical branching and combining device coincident to the constant polarized wave direction of a fiber coil, making a clockwise and a counterclockwise light signal into single polarized waves respectively, and leading them out of the output terminal of the optical branching and combining device. CONSTITUTION:Light emitted by a laser diode 11 is made incident to a lens 16a through a lens 12, Glan-Thompson prism 13, lens 14, and phase plate 15; part of it is reflected by a half-mirror 17 and inputted to a monitor 18, and the remainder is passed through the half-mirror 17, a lens 20, and a rotation lens 21 to obtain light signals having a 90 deg. angle between planes of rotation to each other, which are inputted to a polarization-plane conservative fiber 23. The fiber 23 is a circle with a radius R and the light signals inputted from both ends 23a and 23b propagate in the fiber clockwise and counterclockwise, and is passed through the rotation prism 21 and reflected by the half-mirror 17 to be outputted through a phase plate 19. Namely, almost all the laser light propagates in the optical fiber and phase shifts occurs reversely, so the detection sensitivity close to a logical limit is obtained. | ||||||

| PURPOSE:To shorten the time for measurement by providing a Glan-Thompson prism, halfwave plate and quarter-wave plate supported rotatably with respect to the plane orthogonal with an optical axis between input side and output side optical fibers coupled to a lens. CONSTITUTION:The input side optical fiber 11 of a single mode is connected to a semiconductor laser and the output side optical fiber 21 of a single mode is connected to an optical power meter via a device to be measured (not shown in the figure). The Glan-Thompson prism 4 is formed by sticking two calcite prisms and is so adjusted that linearly polarized light is obtd. in the state of the largest optical power by aligning the main polarization axis and transmission polarization axis of a semiconductor laser. The halfwave plate 5 is capable of arbitrarily setting the main axis of polarization and projects the polarized light at the necessary polarization axis on the device to be measured when said plate is rotated. The quarter-wave plate 6 cancels the elliptical polarization of the polarized light by the double refraction which is generated by the local stress of the optical fiber 21. The P or S polarized light is thereby polarized to the linearly polarized light and is projected to a coupler which is the device to be measured. | ||||||
