A multichannel optical spectrum slicer is able to convert a broad-band continuous spectral light into discontinuous multiple wavelength lights. This spectrum silcer comprise a birefringent device (F1) and linear polarizers (P0, P1). A birefringent device (F1) such as a birefringent single-mode optical fiber or uniaxial single crystal has two polarization axes (x, y) each orthogonal to an optical axis (z). Linear polarizers (P0, P1) are disposed at the input and the output ends of the birefringent device (F1) with the direction of polarization (A) being inclined by about 45° relative to each of the polarization axes (x, y). Further, when birefringence devices (F1, F2) are disposed in plurality between each polarizer (P0-P2), the spectrum separation is enhanced more.

摘要:
A light receiving section of a photocoupler according to the present invention has, for example, a light receiving element, a converting circuit, an oscillator, an updown (U/D) counter, a decoder and a clock signal supply control circuit, and those devices are monolithically integrated therein. When the light receiving element receives light from a light generating section, an output of the converting circuit becomes High. At this time, an output of the decoder is delayed until the U/D counter has counted up to the preset number a clock signal supplied by the clock signal supply control circuit. On the other hand, upon having Low of the output of the converting circuit, the output of the decoder is delayed until the U/D counter has counted down to "0" the clock signal supplied by the clock signal supply control circuit. Therefore, even in the case where noise interferes the output of the converting circuit, since the output of the decoder is delayed until the count value of the U/D counter has reached the preset number or "0" in spite of switching of the operation of the U/D counter, it is not adversely affected by the noise. This results in improved anti-noise characteristics of the photocoupler.
