Controlled coupling of a subwavelength dipole to a photonic crystal microcavity — •V. Sandoghdar, F. Koenderink, and B. Buchler — Laboratory of Physical Chemistry, Swiss Federal Institute of Technology, (ETH), 8093 Zürich, Switzerland

Recently there has been a remarkable progress in the design and fabrication of photonic crystal microcavities with very high quality factors and low volumes. This promises interesting experiments in various fields including Cavity Quantum Electrodynamics and integrated optics. We discuss the coupling between a photonic crystal microcavity and a subwavelength object, such as a single quantum emitter or a scanning probe tip. We show how the cavity modifies the radiative properties of an emitter and how a subwavelength particle modifies the spectral properties of the resonator.
