ABSTRACT:
An optical waveguide device includes an optical waveguide extending straight over a predetermined length, a metal cover layer formed on the optical waveguide at least partly and formed with an opening extending therethrough, and a prism fixedly attached to the metal cover film covering the opening. The prism has an index of refraction higher than that of the optical waveguide and the prism receives an incoming light beam and causes the light beam thus received to be coupled into the optical waveguide through the opening. The device may include a substrate on which the optical waveguide is formed with or without a buffer layer therebetween. A photodetector may also be formed integrally with the optical waveguide at one end thereof for detecting light coupled into and propagating along the optical waveguide. Such a device including a photodetector may be used as an optical component of an optical pick-up for use in an optical information recording and reproducing system.
