Abstract

A resonant microcavity display comprises a thin-film resonant microcavity (20, 50, 60) with an active layer (21). The microcavity (20, 50, 60) comprises a front reflector (22, 52), the active region (21) deposited upon the front reflector, and a back reflector (20, 54) deposited upon the active region (21). The display preferentially emits light that propagates along the axis (27) perpendicular to the plane of the display, due to its quantum mechanical properties. The extrinsic efficiency of this device is increased by the use of thin film construction with anomalous phase dispersion.
