摘要： An optical transceiver module is constituted so as to have an optical transmission module, an optical receiving module, a drive circuit board for driving the optical transmission module and the optical receiving module, and short-circuit means which induces an electrical short circuit between housings of the respective modules or induces an electrical short circuit between ground (GND) terminals of the respective modules on the module sides with respect to the drive circuit board. As a result, in the optical transceiver module, stray capacitance and stray inductance in lead pins, housings, and internal components of optical devices, such as an LD and a PD, are removed, thereby suppressing fluctuations in the potential (GND) of an LD housing which arise during high-frequency driving operation, as well as considerably suppressing electrical crosstalk between the transmission and receiving modules.

摘要： The invention is aimed at providing an optical switch using tilt mirrors, in which easy mounting of the optical components is possible by simplifying the construction, and in which a short spatial propagation distance for the light beam is realized. To this end, the optical switch using tilt mirrors of the present invention comprises; a collimator array and a tilt mirror array each formed with an input section and an output section aligned and integrated, and a shift type turn-back mirror that shifts the optical path of the incident light in a predetermined direction and turns back and outputs this. The construction is such that the light input to the input section of the collimator array is reflected by the input section of the tilt mirror array so that the optical path is changed, and is then sent to the shift type turn-back mirror, and the light which has been shifted and turned back by the shift type turn-back mirror is reflected by the output section of the tilt mirror array and output from the output section of the collimator array.

摘要： Disclosed herein is a terminal device including a photodetector, amplitude detecting circuit, light source, drive circuit, and control circuit. The photodetector receives a first optical signal. The amplitude detecting circuit detects the amplitude of an output from the photodetector. The drive circuit supplies a drive current to the light source so that the light source outputs a second optical signal. The control circuit decreases and increases the drive current according to an increase and decrease in the amplitude detected by the amplitude detecting circuit, respectively. In the case that this terminal device is used with another terminal device to construct a network, the dynamic range of the other terminal device can be reduced. Accordingly, the use of this terminal device can improve the extensibility of the network.

摘要： A wavelength selective switch of the present invention angularly disperses lights output from a plurality of input ports of an input and output optical system, to an X-direction, according to wavelength, by a diffraction grating to supply the dispersed lights to a condenser lens. The condenser lens is arranged so that a center axis thereof is shifted to the X-direction relative to an axis passing through the center of spreading angle to the X-direction of output beams from the diffraction grating, and accordingly, at a non-operating time, the light of each wavelength passed through the condenser lens is incident on each movable mirror being tilted by an offset angle corresponding to a shift amount of the condenser lens. As a result, it becomes possible to block the connection between an input side and an output side at the non-operating time without degrading the performance at an operating time.
