Intersubband Absorption Loss in High-Performance Mid-Infrared Quantum Cascade Lasers

Not Accessible

Your library or personal account may give you access

Abstract

We calculate intersubband absorption loss and report measured waveguide loss for two high-performance mid-infrared quantum cascade laser designs. Intersubband absorption loss accounts for a major component of waveguide loss for these structures.
