We report the observation of a Purcell enhancement of the in-plane spontaneous emission rates of InAsself-assembledquantum dots coupled to a mode of a unidirectional photonic crystal waveguidefabricated in GaAs(001). Three-dimensional finite-difference time-domain simulations predict the existence of high quality-factor modes due to the slow light resonances of the waveguide. These modes have been observed experimentally with microphotoluminescence and produce enhanced in-plane emission when resonant with a quantum dot.We report the observation of a Purcell enhancement of the in-plane spontaneous emission rates of InAsself-assembledquantum dots coupled to a mode of a unidirectional photonic crystal waveguidefabricated in GaAs(001).
