Abstract
Edge-emitting light source and method for fabricating an edge-emitting light source. The edge-emitting light source includes a photonic crystal having at least one waveguide region. An edge-emitting semiconductor structure having a light emitting active layer is incorporated within the at least one waveguide region. Light emitted by the edge-emitting semiconductor structure and within the bandgap of the photonic crystal is confined within the waveguide region and guided out of the photonic crystal through the waveguide region.
Claims20
An edge-emitting light source, comprising:
- a photonic crystal having at least one waveguide region;
- and
- an edge-emitting semiconductor structure having a light emitting active layer incorporated within each at least one waveguide region, wherein light emitted by the edge-emitting semiconductor structure and within a photonic bandgap of the photonic crystal is confined within the at least one waveguide region and guided out of the photonic crystal through the at least one waveguide region.
A method for fabricating an edge-emitting light source, comprising:
- providing a substrate;
- and
- forming a photonic crystal waveguide on the substrate, the photonic crystal waveguide comprising a semiconductor structure formed in at least one waveguide region of the photonic crystal waveguide.
An edge-emitting light-emitting diode light source, comprising:
- a two-dimensional photonic crystal slab having at least one waveguide region extending through the two-dimensional photonic crystal slab;
- and
- an edge-emitting semiconductor structure having a light emitting active layer incorporated within each at least one waveguide region, wherein light emitted by the edge-emitting semiconductor structure and within a photonic bandgap of the photonic crystal is confined within the at least one waveguide region and guided out of the photonic crystal through the at least one waveguide region.
