Light emitting device with omnidirectional reflectors |
摘要 |
A light emitting device includes a semiconductor structure having lateral side faces, and including a light-generating layer, and two omnidirectional reflectors disposed respectively at two sides of the light-generating layer. Each of the omnidirectional reflectors exhibits a periodic variation indielectric constant in such a manner so as to introduce an omnidirectional photonic band gap in a given frequency range such that the radiation generated by the light-generating layer in the frequency range for all incident angles and polarizations can be totally reflected by the omnidirectional reflectors and can be extracted substantially only from the lateral side faces of the semiconductor structure.
