Optical properties of a ZnSSe microcavity fabricated by epitaxial lift-off.

Abstract We have fabricated and studied the optical properties of a planar II–VI ZnSSe microcavity. The MBE grown II–VI epi-layers were subsequently transplanted onto a metal coated GaAs substrate using the epitaxial lift-off technique. Comparison of the emission from the processed (microcavity) and unprocessed (non-microcavity) samples show evidence of spectral filtering and modified directionality which are due to the action of the cavity on the quantum well emission. Reflectance spectra confirm the Fabry-Perot resonance and excition feature are in the same spectral region. These results show that II–VI microcavities can be achieved using lift-off techniques.
