Abstract
A surface plasmon laser structure is formed to include a DFB structure as the 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—Au stripes). The active region, in one embodiment, may comprise a quantum cascade structure.
