We report on the coherent coupling of a single organic molecule to a scannable, tunable and broadband microcavity. The cavity consists of a planar distributed Bragg reflector and a micromirror with a small radius of curvature of 5 µm fabricated with focused ion-beam milling and coated with silver or dielectric multilayers. By integrating a thin organic crystal in the microcavity at liquid helium temperature, we are able to coherently couple individual molecules to a single mode of the cavity. Our experimental and theoretical results show that a single molecule can block the cavity transmission nearly perfectly. We present a strong modification of the phase and photon statistics of a laser beam and demonstrate improvement of single-molecule stimulated emission compared to free-space coupling in a tight focus.
