发明名称 Waveguide-arrayed optical wavelength mutiplexer/demultiplexer and fabrication method of the same
摘要 To provide a waveguide-arrayed optical wavelength multiplexer/demultiplexer in which a mode configuration of a waveguide slab output part is matched to a mode configuration of waveguide array input parts, to achieve a reduced loss irrespective of distances between arrayed waveguides, and a manufacturing method of the same, a wavelength multiplexer/demultiplexer (10) is formed on a substrate (11) with a plurality of input waveguides (12) for inputting wavelength division multiplexed optical signals, an output waveguide (13) for combining the wagelength division multiplexed optical signals to be output, a waveguide array (15) as a set of arrayed waveguides (15b) having predetermined waveguide length differences (DELTAL), an input waveguide slab (14) for interconnecting the plurality of input waveguides (12) and the waveguide array (15), and an output waveguide slab (17) for interconnecting the waveguide array (15) and the output waveguide (13), and the input waveguide slab (14) and the output waveguide slab (17) are configured to have their intended refractivity distributions (16, 19).
