OPTICAL CONNECTING STRUCTURE, OPTICAL MODULE AND MANUFACTURING METHOD FOR OPTICAL CONNECTING STRUCTURE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18031859 titled 'OPTICAL CONNECTING STRUCTURE, OPTICAL MODULE AND MANUFACTURING METHOD FOR OPTICAL CONNECTING STRUCTURE

Simplified Explanation

The patent application describes an optical connection structure that includes an optical waveguide device, an optical fiber, and a self-forming waveguide.

  • The optical waveguide device consists of a substrate, a BOX layer, a first waveguide, and an overcladding.
  • The optical fiber is placed in a V-groove on the substrate.
  • A self-forming waveguide is located between the end face of the optical waveguide device and the end face of the optical fiber.
  • The self-forming waveguide is surrounded by a cladding.
  • The positioning of the optical fiber allows the signal light emitted from the fiber to enter the waveguide.
  • The self-forming waveguide is created by curing a portion of it with resin curing light.


Original Abstract Submitted

An optical connection structure includes an optical waveguide device that includes a substrate, a BOX layer, a first waveguide, and an overcladding in this order, an optical fiber disposed in a V-groove formed in the substrate, a self-forming waveguide disposed between an end face of the optical waveguide device and an end face of the optical fiber, and a cladding disposed around the self-forming waveguide. The optical fiber is positioned so that the end face of the optical fiber faces the end face of the optical waveguide device to cause signal light emitted from the optical fiber to enter the waveguide. The self-forming waveguide is formed with a portion cured by irradiation with resin curing light.
