Title: Optical wavelength demultiplexer
Inventor: SHIRASAKI MASATAKA
IPC: G02B6/293
Filed: 1984-11-19
Abstract: PURPOSE:To reduce the crosstalk by arranging two diffraction gratings so that their diffraction directions are vertical to each other and diffusing circularly the power of scattering due to the grating unevenness of the first and the second diffraction gratings. CONSTITUTION:Two transmission type diffraction gratings 1 and 2 are arranged at a proper interval so that their diffraction directions are orthogonal to each other. If two rays of light A and B different in wavelength are allowed to pass them, the rays A and B are separated from each other by an angle thetain one direction by the first diffraction grating 1 and are separated from each other by the angle theta in the direction orthogonal to said direction by the second diffraction grating 2. That is, an incident light 3 is separated on the same line, and the rays A and B are separated in directions orthogonal to each other, and consequently, the reception interval between the rays A and B is about 2<1/2>theta. Thus, the power per unit area is reduced to reduce the crosstalk between the rays A and B.

Title: Edge filter
Inventor: KITAZAWA TOMOKO
IPC: G02B5/28
Filed: 1986-10-16
Abstract: PURPOSE:To obtain a spectral characteristic satisfactory as an edge filter so that the pass loss in particular is decreased and that the filter characteristic is steepened and the attenuation quantity in a blocking region is increased by forming the filter into the specific constitution including alternately laminated multi-layered films consisting of high refractive index materials and low refractive index materials. CONSTITUTION:The edge filter has no matching layers in the constitution and is simple in production and since the 1st layer is of the high refractive index material 2, the degradation in the accuracy of the film thickness arising from the low refractive index material 3, when used as the 1st layer on the conventional monitor substrate, is prevented and, therefore, the yield is improved. The film thicknesses of at least respective 8 layers on the substrate 1 side and the medium side are shifted by 1/4 or 1/8 wavelength from the optical thickness to form the films of the edge filter. Ripples are thereby decreased to decrease the pass loss. The steepness of the filter characteristic is simultaneously improved and the attenuation quantity in the blocking region is increased, by which the yield is improved.
