本文首次采用衍射光栅刻划机在抛光好的光学玻璃棱镜表面上制作周期为1200条线/毫米的光栅的棱镜-光栅耦合器。把它用于其薄膜折射率即使大于棱镜折射率时
仍然可以在薄膜中有效地激励波导模式。
A grating with 1200 lines/mm has been fabricated by a diffraction grating ruling engine on the surface of a polished optical glass (ZF7) prism for the first time. This device is usually called prism-grating coupler. It has many novel characteristic
and the wave--guide mode can be effectively excited in the film even when the index of the film is higher than that of the prism.
