ABSTRACT
In this letter, we present a unidirectional photonic crystal (PhC) dispersion-based emitter. This device combines a PhC microcavity with a dispersion-based region that is used to produce a unidirectional emission. The three-dimensional finite-difference time-domain method is used to evaluate the performance of the device. The simulation shows a unidirectional emission beam with a small aperture. The principle of this device can be applied in the design of light-emitting diodes or lasers with a unidirection and a small beam aperture in integrated optical circuits. © 2004 American Institute of Physics.
