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. |
其他摘要 | 光电耦合器具有偏振转换装置,用于将从激光源发射的激光转换成偏振光束,该偏振光束具有在圆的正切方向上取向的电矢量,该圆的中心位于光电耦合器的光轴上,并且其相位相位相反。光束被.pi移动。在通过圆心的赤纬线的边界处。转换后的激光的波前是球形的。并且,用于激发从其中心径向传播的波导光的光电耦合器被定位成使得输入耦合效率变得最大。 |
