1. An injection incoherent emitter comprising:

  • a heterostructure comprising;

    at least one active layer;

    cladding layers; and

    ohmic contacts, and at least one emission output area on at least one side of the active layer, the emission output area adjoining at least one of the cladding layers, the emission output area being transparent for emission, the emission output area comprising at least one emission output area layer having a refractive index noaq, where q=1, 2, . . . p is defined as a whole number that designates the ordinal number of the emission output area layer enumerated from a boundary of the emission output area with the heterostructure, the emission output area and the heterostructure together having an effective refractive index nef, the effective refractive index nef of the heterostructure and the emission output area and the refractive index noa1 of the emission output area being selected to satisfy the correlations;
