摘要： An optical receiver including an optical conversion device which converts difference in wavelength into difference in spatial power distribution and pattern recognition element for recognizing patterns of the spatial power distribution and taking out output signals. At the output portion (24) of the optical conversion device spatial power distributions are different for different wavelengths. After converting the spatial power distributions by the pattern recognition element (25A, 25B, 25C, 25D) into electric signals pattern recognition of the signals is performed to regenerate original signals with respective wavelengths. The optical conversion device uses a diffractive grating or a combinations of a optical multimode circuit (22), a optical multimode fiber (20), and a plurality of optical waveguides. The pattern recognition element is constructed by a combination of photo-detector array (25A, 25B, 25C, 25D), and a neural network (27) or a combination of a hologram element, a photo-detector array and a neural network.
