Abstract
High-temperature operation of 5.5 mum strain-compensated InGaAs/InAlAs quan tum cascade lasers with high-reflection (H-R) coating is presented. A thres hold current density of 7.5 kA/cm(2) was observed at the record high temper ature of 470 K using HR coating on both facets with reflectivities of 99.6 and 80.2%, respectively.
