    Abstract: PURPOSE: An ultra-short polarization-independent vertical directional coupler switch is provided to accurately control the thickness between two waveguide core layers to a submicron level by forming an inner cladding layer between two waveguide core layers using epitaxial growth, thereby shortening a light coupling length and operating the switch regardless of light polarization condition. CONSTITUTION: An ultra-short polarization-independent vertical directional coupler switch comprises the first waveguide part(10), the second waveguide part(20), and an inner cladding layer(30) between the first waveguide part and the second waveguide part. At least one of the first and the second waveguide parts is formed on a predetermined substrate(40). The first waveguide part and the second waveguide part are arranged in a vertical direction over the substrate. The first waveguide part has the first core layer(12) and the first outer cladding layer(14). The second waveguide part has the second core layer(22) and the second outer cladding layer(24).
