DISTRIBUTED FEEDBACK SURFACE PLASMON LASER

摘要

A surface plasmon laser structure is formed to include a DFB structure as t he metal carrying layer, thus forming a single mode surface plasmon laser. The DFB structure comprises a multiple layer metallic surface guiding structure (for example, titanium stripes covered with a layer of gold, forming alternating Ti/Au - A u stripes). The active region, in one embodiment, may comprise a quantum cascade structure.
