摘要：
A no polarization dependent waveguide type optical circuit can resolve polarization dependency completely and can reduce reflected return light. An intermediate portion of the two connecting waveguide (9), (10) are formed with S-shaped waveguides of the same shape consisted of respectively two curved waveguides (9B), (9E), (10B), (10E) or two curved waveguides and straight waveguides (9C), (9F), (10C), (10F) connecting the curved waveguides. One or two polarization mode converters are provided in a groove (11) formed across the S-shaped waveguide, and a perpendicular line to an incident surface of light of the polarization mode converter (12) and the S-shaped waveguide forms an angle greater than 0° .
