Light emitting systems
Light-emitting systems, and related components, systems and methods are disclosed.
1 . A light-emitting system including a light-emitting device that comprises:
a multi-layer stack of materials including a light-generating region and a first layer supported by the light-generating region,
wherein:
a surface of the first layer is configured so that light generated by the light-generating region can emerge from the light-emitting device via the surface of the first layer;
the surface of the first layer has a dielectric function that varies spatially according to a pattern;
the pattern has an ideal lattice constant and a detuning parameter with a value greater than zero; and
the light-emitting device is configured so that, when light generated by the light-generating region emerges from the light-emitting device via the surface of the first layer, the light can emerge from the light-emitting system.
