| 英文摘要 | PURPOSE:To easily diminish the spreading of input light and to widen the allowance for errors by providing and optical coupling means before or behind a condensing point by a condensing means. CONSTITUTION:The light emitted from a semiconductor laser 1 is made to the convergent light which has a point F as a convergent point by a condenser lens 2. This light is passed through a polarized light converting element 3 and is thereby polarized to the concentrically and circularly polarized light, the electric field vector of which exists in a concentrical circle tangent direction. The polarized light is then made incident on a circular coupler 5 which has a concentrical circular grating formed on a waveguide layer 4 orthogonal with the optical axis. The coupler 5 is provided before or behind the point F. Since the input light is made into the convergent light or divergent light, the optical coupling means can be provided in the position of sufficiently small spreading of the input light. In addition, the standard deviation of the wave front aberration of the input light is compressed by adjusting a laser beam source or the optical coupling means or condensing means along the optical axis of the laser beam by a sliding means. The deterioration in the coupling efficiency is sufficiently suppressed to small level in this way and the allowance to the errors is widened. |
