Abstract:
1. A method of manufacturing an optical waveguide platform with a hybrid-integrated optical transmission device and optical active device, comprising: sequentially depositing a lower cladding layer and a core layer of an optical waveguide on a substrate; forming a spot expanding region by reducing a line width or a thickness of the core layer in a tapering manner; depositing an upper cladding layer of the optical waveguide on the core layer; forming a terrace by partially etching the upper cladding layer, the core layer and the lower cladding layer of the optical waveguide; flip-chip bonding the optical transmission device to the formed terrace; and flip-chip bonding the optical active device on the upper cladding layer of the optical waveguide adjacent the spot expanding region and at a front end of the optical transmission device on the optical waveguide.
