Wavelength multiplexer/demultiplexer with light condensing function
专利汇可以提供Wavelength multiplexer/demultiplexer with light condensing function专利检索，专利查询，专利分析的服务。并且PURPOSE:To separate the divergent light having many wavelength components into individual wavelength components and to condense them with a simple constitution by providing a diffraction grating having the condensing function in a waveguide. CONSTITUTION:An Si-N layer 2 and a waveguide layer 3 are laminated on a substrate 1 consisting of a heat-resistant glass, and an optical fiber 4 for input and a photodetector 5 consisting of a light receiving element array are connected to them. The Si-N layer 2 is roughened to form a diffraction grating 6, and its each slit face is set to such shape that the light of each wavelength is converged in a prescribed position. Consequently, the divergent light made incident from the optical fiber 4 goes in the waveguide layer 3 and is separated into light having respective wavelengths by the diffraction grating 6, and the light is converged in channel waveguides 7 corresponding to respective wavelengths and outputted from the photodetector 5. Thus, a lens is unnecessary and light is separated and condensed for each wavelength by the small-sized device.，下面是Wavelength multiplexer/demultiplexer with light condensing function专利的具体信息内容。
