Abstract
Embodiments are notably directed to a vertical microcavity. The vertical microcavity includes a first reflector and a second reflector, each of which includes one or more material layers extending perpendicular to a vertical axis x. The cavity may further include a confinement region extending between the first reflector and the second reflector, so as to be able to confine an electromagnetic wave. The confinement region may include a single layer material, which is structured so as to create an effective refractive index variation for the electromagnetic wave to be confined, in an average plane of the single layer material, perpendicularly to said vertical axis x. Additional examples are further directed to related microcavity systems and methods of fabrication.
