摘要： In the forward direction, the light from an input fiber is polarized and separated in a polarized light separating and combining element, the separated polarized light is rotated by a polarized light rotating element, dispersed according to wavelength by a wavelength dispersing element, rotated again by the polarized light rotating element, and is further rotated by a phase plate, thereby combining the polarized lights in the polarized light separating and combining element, so that only the light of a desired wavelength is coupled with the optical fiber. In the reverse direction, the light from the output fiber is not coupled with the input fiber, and hence the light propagation direction is defined in one direction in the disclosed optical circuit. A light transmission system and method using this optical circuit is also presented.

摘要： On one end side of a converging rod lens are provided a first and second input optical fibers and a first and second output optical fibers. On the other end side of the converging rod lens is provided a reflecting mirror. Between the converging lens and the first and second input and output optical fibers is provided a birefringent element for resolving a ray which passes therethrough into an ordinary ray and an extraordinary ray. In the optical paths of the first and second output optical fibers between the converging rod lens and birefringent element is placed a compensator for rotating 45 degrees the plane of polarization of a ray which passes therethrough. The reflecting mirror reflects incident rays from the first and second input optical fibers to the first and second output optical fibers. Between the converging rod lens and the reflecting mirror is provided a magneto-optical element for rotating 22.5 degrees the plane of polarization of a ray which passes therethrough. The rays emitted from the first and second input optical fibers have their planes of polarization rotated 90 degrees by the magneto-optical element and compensator.

摘要： An input light beam is applied to a diffraction element. The diffraction element is moved relative to a path of the input light beam while the input light beam is diffracted by the diffraction element and is thereby made into a diffracted light beam traveling from the diffraction element. A portion of the diffracted light beam is detected, and an intensity of the received diffracted light beam is also detected. In addition, a peak of the detected intensity of the received diffracted light beam is detected while the diffraction element is moved relative to the path of the input light beam. A position of the diffraction element is detected at which the detected peak of the detected intensity occurs. The position of the diffraction element is controlled on the basis of the detected position at which the detected peak of the detected intensity occurs.

摘要： In a package mounting an optical semiconductor module, an optical semiconductor module is supported by a supporter fixed on a metallic base such that the optical semiconductor module is inclined relative to the circuit board. Further, a lead pin of the optical semiconductor module is set as high as a signal input/output line of a high frequency circuit board. The lead pin is fixed at the shortest distance to the signal input/output line with solder. Thus, the performance of the optical semiconductor module is not deteriorated, and the other components on the circuit board are not affected. A circuit board may be arranged below the optical semiconductor module.
