Patent JP-H07159633-A (JP)
Title: Optical waveguide device
Inventor: MATSUURA KEIJI
IPC: G02B6/122
Filed: 1993-12-02
Abstract: PURPOSE:To miniaturize an optical waveguide device by disposing a low- refractive index region between optical waveguides after a branch part, thereby enabling shortening of the optical waveguides of the branch region and shortening the length of the branch regions. CONSTITUTION:A material MgO which lowers the refractive index of a substrate 11 is diffused into the substrate between the optical waveguides after the branching part 13 of the optical waveguide 12 (referred to as an inter-waveguide region 14). The incident light on the optical waveguide 12 advances through the branch part 13 and the branch region 15 to the optical waveguides 16, 17. Since the refractive index of the inter-waveguide region 14 is drastically lowered than the refractive index of the substrate 11, the light propagating in the optical waveguides 16, 17 is not radiated to the inter-waveguide region 14. Then, the spacing between the optical waveguides 16 and 17 is not largely widened and the coupling of the light beams propagating in the optical waveguides 16, 17 to each other is prevented. The length of the branch region is made shorter by maintaining the small spacing between the optical waveguides and the size over the entire part of the optical waveguide device is reduced.
