Quantum cascade lasers based on guided modes at a metal-semiconductor interface
(1998)OSA Technical Digest ~ Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics (CLEO '98)Summary form only given. Planar waveguides for long-wavelength quantum cascade (QC) lasers require thick cladding layers. This prolongs and complicates the growth and processing procedures of these lasers. In this paper we demonstrate that optical waveguiding for a laser in this wavelength range can also be achieved using electromagnetic surface waves at a metal-semiconductor interface directly above the active region of the laser.

Strain-compensated In 0.7Ga 0.3As-Al 0.6In 0.4As quantum cascade lasers for 3-5 mum operation
(1998)OSA Technical Digest ~ Technical Digest. Summaries of papers presented at the Conference on Lasers and Electro-Optics (CLEO '98)Summary form only given. We report quantum cascade lasers based on strained InGaAs-AlInAs at 3.5 /spl mu/m with optical powers up to 5 mW to T 280 K. Operations of the first buried-heterostructure QC lasers at 5 /spl mu/m also will be discussed.Other Conference Item -
