摘要： Optical waveguide devices (100) based on optical coupling of different modes (110, 130) by using a mediating mode (120). Such waveguide devices (100) generally have at least to coupling regions (104, 106). The first coupling region (104) couples an output mode and the mediating mode, and the second one (106) couples the mediating mode and an input mode that copropagates with the output mode. Under proper conditions, the energy in the input mode can be completely transferred to the output mode, without energy loss to the mediating mode (120).

摘要： An optical filter comprises a multi-mode waveguide (W2) and a single-mode waveguide (W1, W3) coupled in series, the interference of different modes at the multiple-mode/single-mode interface being effective to filter an optical signal propagating through the waveguides to provide a desired wavelength response characteristic. The offset between the waveguides may be varied to control the filter characteristic. The filter may be formed in the cavity of a laser to produce an output having a comb-filter characteristic. It may be used as channel selector in WDM systems.

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.
