ABSTRACT:
An integrated type optical waveguide device includes an input section which contains at least one first optical waveguide and has at least one input end and a plurality of output ends. A phase shifter section has a plurality of second optical waveguides, each of which has one output end and one input end coupled with a corresponding one of the plurality of output ends of the input section. An output section contains at least one third optical waveguide and has at least one output end and a plurality of input ends, each of which is coupled with the output end of a corresponding one of the plurality of second optical waveguides. A material of each of the plurality of second optical waveguides is different from a material of each of the first and third optical waveguides.
