REFLECTION GRATING |
摘要 |
A planar reflecting grating is described which is suitable for use in an optical multiplexer or demultiplexer. This grating comprises a periodic structure of elongated areas which are formed at constant distances from each other in a thin light-conducting layer deposited on a substrate. In their longitudinal directions, the areas have periodic ridges, corresponding ridges extending parallel to each other. |
