Abstract
A resonant microcavity display (20) having microcavity with a substrate (25), a phosphor active region (50) and front and rear reflectors (30 and 60). The front and rear reflectors may be spaced to create either a standing or traveling electromagnetic wave to enhance the efficiency of the light transmission.
