Abstract:
A method for manufacturing an optical waveguide device, the method comprising:disposing a plurality of optical waveguides on a first substrate in a matrix, each of the plurality of optical waveguides comprising a core having a selected number of branch points N for propagating light, and a cladding layer surrounding the core, wherein each length of sides of each grid in the matrix being X and Y, and a length of the core extending in the X direction being Z; disposing a plurality of functional portions on a second substrate; joining the first substrate and the second substrate together so that each of the plurality of optical waveguides opposes to a respective one of the functional portions; forming a plurality of grooves at each of the branch points, the distance between the grooves being P and an angle of each of the grooves being &thgr; (0Â°X=MÂ·P/sin &thgr;(where M is natural number) Y=P/cos &thgr;Z&lE;(N+1)Â·P/sin &thgr;; and dividing the joined first and second substrate to a respective optical waveguide device.
