Mesa geometry semiconductor light emitter having chalcogenide dielectric coating

Mesa geometry semiconductor light emitter having chalcogenide dielectric coating

In a mesa geometry semiconductor laser, a patterned dielectric coating (16) 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.
