摘要: In a single mode optical waveguide having substrate (1), cladding layer (3) formed on the core portion (2) embedded in (3), and an elongated member (4a, 4b; 14; 14a, 14b) for applying stress to or relief groove (5a, 5b; 64) relieving from along (2). A position, shape material of are determined such way that stress-induced birefringence produced accordance with difference thermal expansion coefficient between (1) is desired value.
