OPTO-ELECTRIC HYBRID MODULE |
摘要 |
An opto-electric hybrid module is provided, which is excellent in bending resistance and optical element mountability. In the opto-electric hybrid module, a light-path core of an optical waveguide is provided on a surface of an under-cladding layer, and non-light-path dummy cores are provided on opposite sides of the light-path core in spaced relation to the light-path core as projecting from the surface of the under-cladding layer. An electric circuit having mounting pads is provided on top surfaces of the dummy cores. An over-cladding layer is provided on side surfaces and a top surface of the light-path core, and projects to cover the core. The non-light-path dummy cores each have an elastic modulus that is set higher than the elastic modulus of the under-cladding layer and the elastic modulus of the over-cladding layer. The optical element is mounted on the mounting pads, and positioned above the projecting over-cladding layer. |

1. An opto-electric hybrid module comprising:
an optical waveguide; an electric circuit provided directly on the optical waveguide and comprising mounting pads; and an optical element mounted on the mounting pads; wherein the optical waveguide includes an under-cladding layer; a linear light-path core provided on a surface of the under-cladding layer as projecting from the surface of the under-cladding layer; an over-cladding layer provided on side surfaces and a top surface of the light-path core to cover the light-path core, thereby the optical waveguide is formed as having a projection in shape; and non-light-path dummy cores provided on opposite sides of the light-path core in predetermined spaced relation to the light-path core, each of the non-light-path dummy cores having a higher elastic modulus than the under-cladding layer and the over-cladding layer; wherein the mounting pads are provided on top surfaces of the non-light-path dummy cores, and the optical element mounted on the mounting pads is positioned above a portion of the over-cladding layer which covers the top surface of the light-path core. |
