Title:
OPTICAL WAVEGUIDE AND OPTICAL WAVEGUIDE STRUCTURE
Document Type and Number:
Japanese Patent JP2008304947
Kind Code:
A
Abstract:

To provide an optical waveguide and an optical waveguide structure excelling in heat resistance, low in water absorbing properties and kept low in material cost.

The optical waveguide structure 9 has an optical waveguide 90 having a core layer 93 comprising a core part 94 and a clad part 95 lower in refractive index than the core part 94, and clad layers 91, 92 provided in contact with both faces of the core layer 93 and lower in refractive index than the core part 93; and conductor layers 901, 902 provided on both faces of the optical waveguide 90. The clad layers 91, 92 are composed of a norbornene-based polymer as a main material. It is preferable that the norbornene-based polymer is expressed by a formula, wherein R represents a 1-10C alkyl group, a represents an integer of 0-3, b represents an integer of 1-3, and p/q is 20 or less.
