| 英文摘要 | A photocoupler has a polarization converting device for converting laser light emitted from a laser source to a polarized beam of light having electric vectors oriented in a direction of a tangent of a circle having its center on an optical axis of the photocoupler and the phase of which beam is shifted by .pi. at the boundary of a declination line passing the center of the circle. The wave front of the converted laser light is spherical. And, a photocoupler for exciting a waveguided light which propagates radially from the center thereof is positioned so that the input coupling efficiency becomes maximum. |
