摘要： An arrayed waveguide grating includes: at least one first waveguide; a first slab waveguide connected to the at least one first waveguide; a plurality of second waveguides; a second slab waveguide connected to the plurality of second waveguides; and an arrayed waveguide. The arrayed waveguide includes: M channel waveguides connected between the first slab waveguide and the second slab waveguide, wherein M is a natural number; and a phase correcting portion configured to provide a predetermined phase to at least a part of the M channel waveguides by one or both of a width and a length of the at least the part of the M channel waveguides being changed.

摘要： There is provided a SSC chip whose yield may be improved and whose processing steps may be simplified as compare to those of a prior art PLC chip having a light waveguide circuit to which a spot-size converter (SSC) is added, a fiber array attached with the SSC chip, a PLC module attached with the SSC chip and a method for manufacturing the SSC chip. The SSC chip has four spot-size converters and is fabricated separately from a PLC chip. Each SSC has a straight waveguide having the same core width and height with an end of an input/output waveguide of the PLC chip, a horizontally tapered waveguide in which the core width is enlarged in a tapered shape in the horizontal direction from the core width of the straight waveguide, a vertically tapered waveguide in which the core height is enlarged in a tapered shape in the vertical direction from the core height of the horizontally tapered waveguide and a spot-size enlarged portion whose core width and core height are both enlarged. Because it is unnecessary to fabricate the SSC at the end of the input/output waveguide of the PLC chip, a yield of the PLC chip may be improved.
