Abstract
A light-emitting device having a self-cooled semiconductor laser having a laser cavity.
Claims20
A light-emitting device comprising:
- a self-cooled semiconductor laser, said self-cooled semiconductor laser comprising:
- a laser resonator with a waveguide having a core and bound by a slab photonic-crystal structure that is defined in a cubic, hexagonal, or complex photonic-crystal lattice fabricated in the same structure as said semiconductor laser;
- nanoemitters having anti-Stokes photoluminescence when excited by an internal laser emission, said nanoemitters are located in said core of said waveguide;
- said waveguide made of a wider-bandgap semiconductor material than said nanoemitters;
- and
- wherein said nanoemitters are quantum dots.
