| 英文摘要 | PURPOSE:To emit a complete parallel beam out by structuring part of a two-dimensional optical waveguide formed on a plane substrate so that plural single- mode three-dimensional optical waveguides where light is confined laterally adjoin one another at constant intervals, and coupling the respective single-mode optical waveguides optically. CONSTITUTION:Projection light from a semiconductor laser 6 is guided into a waveguide layer 3 by end surface coupling and propagated while spreading. The light is converted by a Fresnel lens 4 made of SiN4 into nearly collimated light, which is coupled with plural single-mode waveguides made of SiN5. The direction of the light propagated in the single-mode waveguide part 5 is completely equal to the stripes of respective single-mode waveguides, so the light is propagated as complete collimated light. Further, periodic variation in effective refractive index is formed on the surface of the single-mode waveguide 5 made of a loading layer to an about 300Angstrom depth, and consequently the propagated light is emitted out. The emitted light is converged by an optical lens nearly to a diffraction limit and a complete parallel beam is formed. |
