摘要： An object of this invention is to cancel a polarization dependence of a transmission center wavelength due to the waveguide birefringence in an array waveguide and a slab waveguide in an array waveguide diffraction grating type optical multiplexer/demultiplexer filter applied for optical communication, particularly, wavelength split multiplexing system. In order to achieve the object of this invention, a polarization mode convertor converts the TE mode in a waveguide to the TM mode and the TM mode to the TE mode. This conversion function makes it possible to cancel the polarization dependence of the transmission center wavelength due to the waveguide birefringence in the array waveguide and the slab waveguide in front of and behind the polarization mode convertor.

摘要： A guided-wave circuit module includes a guided-wave circuit chip having an input waveguide part and an output waveguide part at the ends thereof, a guided-wave circuit part having a predetermined function and positioned between the input waveguide part and the output waveguide part; and a holder for supporting the guided-wave circuit chip, wherein the guided-wave circuit part of the guided-wave circuit chip does not come in contact with the chip holder; at least part of the input and output waveguide parts of the guided-wave circuit chip is fixed to the holder with a fixing agent; and the packaged chip does not have a warp which leads to deterioration of characteristics. A fixing agent having a high hardness is applied to the periphery of the endfaces of the input and output waveguide parts of the guided-wave circuit module and to the periphery of the fiber endfaces of the optical fiber array connected to the module. Therefore, these endfaces can accurately be polished and the waveguide can be connected to the optical fibers at a sufficiently low fiber connection loss and a high return loss.

摘要： A system for judging success or failure of a work of a robot includes a position command generating unit, a contact position detecting unit, and a work success/failure judging unit. The position command generating unit generates a position command enabling movement of a fingertip of the robot so that a position and posture detecting unit, which is attached to the fingertip of the robot and has an elastic transformation area, is brought into contact with a predetermined position relating to a work target after the predetermined work is performed for the work target by the robot. The contact position detecting unit calculates a contact position that is a position of a tip end of the position and posture detecting unit at the time of being in contact with the predetermined position based on a value of an external force applied to the fingertip and the position of the tip end of the position and posture detecting unit. The work success/failure judging unit judges the predetermined work to be successful when the calculated contact position is within a predetermined range and judges the predetermined work to be failed when the calculated contact position is not within the predetermined range.

摘要： An apparatus has a parameter initial value calculator, a force reference impression part, an evaluation data measurement part, an allowable value setting part, a viscosity parameter calculator, an end determining part, and an inertia parameter adjusting part. The force reference impression part intermittently supplies a force reference to an impedance controller. The evaluation data measurement part measures setting time of time response, an overshoot amount, and the number of vibration times. The allowable value setting part sets allowable values of the overshoot amount and the setting time. The viscosity parameter calculator calculates a viscosity parameter with which the setting time becomes shortest. The end determining part determines the end or continuation of the process by comparing the adjustment values with the allowable values. The inertia parameter calculator adjusts the inertia parameter according to the adjustment values of the overshoot amount and the setting time.

摘要： In an optical interferometer, polarization dependence attributable to the optical path difference has conventionally been eliminated by inserting a half-wave plate at the center of the interferometer. However, light induced by polarization coupling produced in directional couplers used in the optical interferometer causes interference having different interference conditions from those of the normal light. Polarization rotators that effect any one of 90° rotation and −90° rotation of all states of polarization of incoming light are inserted in the optical interferometer, and thereby the interference conditions of light induced by polarization coupling are made the same as those of the normal light. Each of the polarization rotators is implemented by using two half-wave plates and by varying an angle of combination of these half-wave plates. Alternatively, each of the polarization rotators is implemented through a combination of one half-wave plate and a waveguide having birefringence properties.

摘要： A demodulator is provided for a multilevel differential phase shift keyed signal, capable of eliminating polarization dependence due to birefringence and polarization coupling-induced light resulting from a waveguide structure, and also, polarization dependence due to dynamic birefringence produced at the time of driving a variable phase adjuster. The demodulator is configured of an optical delay line interferometer of a waveguide interference type. The S/N ratio of a demodulated signal in the demodulator formed by the optical delay line interferometer can be also improved. Further, both the polarization dependence and the temperature dependence of the optical delay line interferometer can be reduced. The disposition of a polarization converter and groves filled with a temperature compensation material makes it possible to provide a circuit configuration suitable for eliminating the polarization dependence and the temperature dependence of the optical delay line interferometer.
