Corrugated-sidewall interband cascade lasers with single-mode midwave-infrared emission at room temperature
C. S. Kim, M. Kim, W. W. Bewley, J. R. Lindle, C. L. Canedy et al.
We report interband cascade lasers operating in a single spectral mode (lambda[approximate]3.6 [mu]m) at 530 degrees C. A corrugated pattern etched into both sidewalls of the 6- and 9-[mu]m-wide ridges serves to suppress higher-order lateral modes by increasing their loss, and also provides a four ... [Appl. Phys.
