摘要： A wavelength selective optical switch of the present invention separates a WDM light emitted from an input port of an input and output optical system, according to wavelengths, by a diffraction grating, and thereafter, condenses the lights of respective wavelengths on MEMS mirrors respectively corresponding to the respective wavelengths, in a mirror array, to reflect them by a condenser optical system, to thereby switch optical paths for the respective lights. The condenser optical system is configured by combining a plurality of lenses whose focal distances are different from each other, and positions in an optical axis direction of the lenses are adjustable by a slide mechanism. Thus, despite an error in the focal distances of the condenser lenses, in a mounting angle of a spectral element or the like, a beam pitch at the condensing positions of the lights of respective wavelengths can be coincident with a mirror pitch in the mirror array.

摘要： A wavelength selector switch includes first and second refracting plates, an optical splitter, first and second optical systems, an optical coupler polarization controller, and second refracting plate. The first refracting plate refracts the second wavelength-multiplexed light beam. The optical splitter spatially splits into a plurality of wavelength components light beams. The first optical system changes the wavelength components into parallel light beams. The polarization controller selectively changes a polarization angle of each of the parallel light beams. The second optical system condenses the parallel light beams. The optical coupler multiplexes into a third wavelength-multiplexed light beam the parallel light beams condensed. The second refracting plate directs wavelength components of the third wavelength-multiplexed light beam to the first and second optical output ports depending on their polarization angles.

摘要： A microcomputer that can process plural tasks time-divisionally and in parallel, wherein one of a plural programs described by one of the tasks is described as a looped specific task in which the increment of program addresses is fixed, a program counter is usable as a timer counter, a peripheral function instruction is described in the specific task, the peripheral function instruction is set so as to indicate one or more general-purpose registers as an operand. The CPU executes the peripheral function instruction as one instruction and achieves information needed to execute the instruction by a general-purpose register and stores the execution result into the general-purpose registers. An instruction code encoding system includes an operation code and plural operands for indicating operation targets of an instruction in an instruction code and executing an instruction indicated by the operation code on the operation targets. When the operation targets indicated by the plural operands are set to a combination in which an execution result does not vary, the processing corresponding to an instruction different is executed.
