Abstract :
In this paper, a novel microcavity light emitting device is demonstrated to produce pure circularly polarized light with simultaneous control over emission bandwidth and center wavelength. This is achieved by sandwiching fluorescent molecules (Alq3) between two sculptured thin film (STF) chiral reflectors to form a resonant microcavity device of circular polarization selectivity, and optically pumping the device with unpolarized violet light
