Abstract
A vertical cavity surface-emitting laser (VCSEL) is disclosed. The VCSEL includes a layer that at least partially defines an optical cavity having an optical axis. The VCSEL further includes a resonant reflector layer extending across at least part of the optical cavity. The resonant reflector layer has a refractive index that does not abruptly change laterally across the optical cavity. The refractive index of the resonant reflector layer includes contributions from a first material having a first refractive index and a second material having a second refractive index. At least one of the first material and the second material includes a polymer.
