英文摘要	An optical waveguide structure capable of optically coupling a surface type optical device, such as a surface emitting laser diode or a photodiode, and a transmission medium, such as an optical fiber, located so that their light output surface and light input surface will form an angle of about 90° with each other simply and easily. The optical waveguide structure comprises a first clad section having a curved surface for gradually turning the direction in which light travels almost squarely and a groove formed in the curved surface along the direction in which light travels, a core section which is made from a transparent material with a refractive index higher than the refractive index of the first clad section and with which the groove is filled in, and a second clad section which covers an exposed surface of the core section and the curved surface of the first clad section and which is integrated with the first clad section.
