Abstract

This study demonstrates that optical waveguiding for a laser in wavelength range 10-15 μm can be achieved using electromagnetic surface waves at a metal-semiconductor interface directly above the active region of the laser. No cladding layer is needed. The interface-guided modes are transverse-magnetic modes existing at the interface between a metal and a semiconductor, which have dielectric constants opposite in sign.
