Planar lens and low order array multiplexer. |
摘要 |
<p>An integrated optic device useful as a planar lens or a low order array multiplexer comprises a pair of optical couplers (21, 22) and an array of plural waveguides extending between the couplers in an "S" configuration to provide closely spaced optical path lengths. An "S" configuration provides equal path lengths for an optical lens. Incremental lengths (30) added to the "S" in the region between curve reversal can provide small path length increments for a low order array multiplexer or demultiplexer. <IMAGE></p> |
