Abstract

Here, we emphasize the importance of a bottom reflector for achieving unidirectional far-field emission. As a result, over 80% of photons generated inside the cavity can be collected within a divergence angle of ±30° from the top. We also discuss interesting analogy in which the nanocavity-bottom reflector coupled system is treated as a point-like emitter in front of a mirror. Based on such a view point, the observed directivity is explained by using a comprehensive interference model. Finally, we propose a very practical form of an efficient photonic crystal nanolaser bonded on a flat metal surface, which may enable current injection and room-temperature continuous-wave operation.
