| 英文摘要 | An optical coupling circuit element providing one transparent substrate (7), a first micro Fresnel lens (11) formed on one side surface (31) of said substrate, and a second micro Fresnel lens (21) formed on the other side surface (31b) of said substrate, so that coherent light incident into said first micro Fresnel lens is projected, through said transparent substrate, on said second micro Fresnel lens to be left therefrom as a collimating beams, which is useful for directing light emitted from coherent source such as semi-conductor laser (5) to optical communication means such as optical fiber (6) for condensation. |
