MESA GEOMETRY SEMICONDUCTOR LIGHT EMITTERS HAVING CHALCOGENIDE DIELECTRIC COATING

In a mesa geometry semiconductor laser, a patterned dielectric coating used to define the stripe geometry contact on the top the mesa and to provide significant waveguiding comprises a chalcogenide glass. Applications to intersubband (e.g., quantum cascade) lasers are specifically described.
