Broadly continuously tunable slot waveguide quantum cascade lasers based on a continuum-to-continuum active region design

We report our progress in the development of broadly tunable single-mode slot waveguide quantum cascade lasers based on a continuum-to-continuum active region design. The electroluminescence spectrum of the continuum-to-continuum active region design has a full width at half maximum of 440 cm−1 at c...
