摘要： PROBLEM TO BE SOLVED: To provide a variable dispersion compensator capable of drastically reducing a ripple produced in a dispersion characteristic of a variable dispersion compensator of the conventional technique using a spatial phase modulator having an LCOS structure and having an operable band width which is larger than that in the conventional technique, whereby an application possibility other than the dispersion compensator is widened by removing the ripple produced in the dispersion characteristic. SOLUTION: In order to reduce reflection light in a gap part between retardation imparting functional parts, a transparent glass substrate or the like is used as a back surface substrate and, thereby, the reflection light is caused to disappear. An optical signal on the retardation imparting functional parts is reflected by a mirror array formed on the innermost surface of the back surface substrate. A mirror array having an electrode function can be also formed on the surface side opposite to a common transparent electrode on the back surface substrate. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an optical signal selection switch where crosstalk occurring between output ports is suppressed.SOLUTION: The optical signal selection switch includes: at least one input port; a plurality of output ports; a condenser lens which condenses an optical signal emitted from the at least one input port; and deflecting means which gives phase shifts to the optical signal condensed by the condenser lens and reflects the optical signal so that the optical signal to which the phase shifts are given is coupled with the output ports via the condenser lens. A period of a phase-shifted waveform in one output port due to the deflecting means is different from 1/i (i is an integer other than 0) of periods of the phase-shift waveform in the other output ports due to the deflecting means, so that crosstalk between ports can be suppressed because, in one output port, diffracted light of second and higher orders of the other output ports are not coupled.

摘要： PROBLEM TO BE SOLVED: To provide an optical signal processor that uses a spherical single lens with cost-saving in mind and that reduces optical coupling loss, wherein: a conventional optical signal processor, in a spatial optical system including a single lens, has insufficient reduction in optical coupling loss caused by spherical aberration of a condensing lens; and the face aberration could be reduced through utilization of an aspheric lens or use of a plurality of lenses, which needs preparation of a large number of expensive lenses. SOLUTION: The optical signal processor, on the basis of a spherical aberration caused by lenses in use, is configured to have an array waveguide of AWG so that equiphase wavefront can be formed to pre-compensate this spherical aberration. Instead of reducing aberration of a spherical lens, focusing on the wavefront of an optical signal emitted from the AWG, an array waveguide is configured in a manner that an optical signal of non-planar wave is emitted to the spatial optical system.
