Distributed feedback surface plasma vibrator laser

A surface plasmon laser structure (10) 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 (30) covered with a layer of gold...

More Information
Summary:A surface plasmon laser structure (10) 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 (30) covered with a layer of gold (32), forming alternating Ti/Au - Au stripes (30,32)). The active region (12), in one embodiment, may comprise a quantum cascade structure.
