US 2016/0238807 A1 · OPTO-ELECTRIC HYBRID MODULE

Abstract

An opto-electric hybrid module is provided. In the opto-electric hybrid module, a core and an electric circuit including electric circuit body portions and mounting pads are provided on a surface of an under-cladding layer of an optical waveguide. An optical element is mounted on the mounting pads with its electrodes in abutment against the mounting pads. The core is covered with the over-cladding layer, and a center portion of the optical element is positioned above a portion of the over-cladding layer covering a top surface of the core. A portion of the electric circuit excluding the mounting pads and a surface portion of the under-cladding layer present between the electric circuit body portions of the electric circuit and present between the electric circuit body portion and the mounting pad are covered with a core material layer formed of the same material as the core.

Dependent claims

An opto-electric hybrid module comprising:

an optical waveguide including an under-cladding layer, a linear light-path core provided on a core formation portion of a surface of the under-cladding layer as projecting from the surface of the under-cladding layer, and an over-cladding layer covering only the core;
an electric circuit provided directly on the optical waveguide and including mounting pads;
and
an optical element mounted on the mounting pads;
wherein the optical element is positioned at a predetermined position above a portion of the over-cladding layer covering a top surface of the light-path core;
wherein the electric circuit is provided on a portion of the surface of the under-cladding layer other than the core formation portion and is covered with a core material layer formed of the same material as the core.
