Title:
OPTICAL WAVEGUIDE AND METHOD FOR MANUFACTURING OPTICAL WAVEGUIDE
Document Type and Number:
WIPO Patent Application WO/2024/084681
Kind Code:
A1
Abstract:
Provided is an optical waveguide comprising: an optical propagation path that includes an organic electro-optic polymer material; and a layered structure that has a first layer that covers at least a portion of the optical propagation path and prevents oxygen permeation from outside toward the optical propagation path, and a second layer that prevents moisture permeation from outside toward the first layer. The first layer may include Al2O3 and the second layer may include SiO2. The layered structure may have a three-layer structure formed by stacking, in order, the second layer, the first layer, and a third layer that prevents moisture permeation from the optical propagation path toward the first layer.
