Abstract
The wavelength dispersion of the phase shift on reflection that is inherent in dielectric Bragg mirrors can be used to phase compensate resonant-cavity-based devices such as multiple quantum well asymmetric Fabry–Perot spatial light modulators and vertical cavity surface-emitting lasers. We demonstrate the post-growth ability to accurately fine-tune the location of the Fabry–Perot minima in a resonant cavity by employing either a normal or inverted dielectric mirror configuration. The dielectric multilayer mirrors are composed of alternating quarter-wave layers of MgF2 and Sb2S3, and exhibit broadband reflectivities.
