Abstract
Light-emitting devices, and related components, systems and methods are disclosed. The light-emitting device can include a multi-layer stack of materials including a light-generating region and a first layer supported by the light-generating region. A surface of the first layer can be 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 can have a dielectric function that varies spatially according to a pattern that has an ideal lattice constant and a detuning parameter with a value greater than zero.
