Document Type and Number:
WIPO Patent Application WO/2014/188552
Kind Code:
A1
Abstract:
The present invention relates to an optical semiconductor integrated element and a method for manufacturing the optical semiconductor integrated element, solves difficulty in element manufacture, and reduces optical transmission loss. The present invention is provided with a stripe-shaped waveguide configured from a laminated structure wherein at least a first conductivity-type lower cladding layer, a waveguide core layer, and an upper cladding layer are laminated, and the upper cladding layer is formed using a second conductivity-type upper cladding layer, and an i-type upper cladding layer, which has a bent portion by being shifted in the perpendicular direction with respect to the main extending direction of the waveguide.
