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 radius of curvature of 5 µm fabricated with focused ion-beam milling and coated with silver. By integrating an organic matrix in the microcavity at liquid helium temperature, we are able to coherently couple individual molecules to the single mode of the cavity. Our results show that a single molecule can attenuate 38% of the light stored in the cavity. We also demonstrate four-fold improvement of single-molecule stimulated emission compared to free-space coupling in a tight focus. Our experimental approach based on a microcavity with low mode volume and low quality factor paves the way for the realization of a series of nonlinear and collective quantum optical effects.
