Few-photon Coherent Nonlinear Optics with a Single Molecule

Vahid Sandoghdar

This talk presents recent experiments on the nonlinear interaction of a single organic molecule with two weak continuous-wave narrow-band laser beams in a tight focus, in a dielectric nanoguide and in an ultrasmall Fabry-Perot micocavity.

Turning a molecule into a coherent two-level quantum system

Wang, D., Kelkar, H., Cano, D. +5 more

The use of molecules in quantum optical applications has been hampered by incoherent internal vibrations and other phononic interactions with their environment. Here we show that an organic molecule placed into an optical microcavity behaves as a coherent two-level quantum system. This allows the observation of 99% extinction of a laser beam by a single molecule, saturation with less than 0.5 photons and non-classical generation of few-photons super-bunched light. Furthermore, we demonstrate efficient interaction of the molecule–microcavity system with single photons generated by a second molecule in a distant laboratory. Our achievements represent an important step towards linear and nonlinear quantum photonic circuits based on organic platforms.The use of molecules in quantum optical applications has been hampered by incoherent internal vibrations and other phononic interactions with their environment.

Single-Photon Spectroscopy of a Single Molecule

Yves L. A. Rezus, Samuel G. Walt, R. Lettow +4 more

Efficient interaction of light and matter at the ultimate limit of single photons and single emitters is of great interest from a fundamental point of view and for emerging applications in quantum engineering. However, the difficulty of generating single-photon streams with specific wavelengths, bandwidths, and power as well as the weak interaction probability of a single photon with an optical emitter pose a formidable challenge toward this goal. Here, we demonstrate a general approach based on the creation of single photons from a single emitter and their use for performing spectroscopy on a second emitter situated at a distance. While this first proof of principle realization uses organic molecules as emitters, the scheme is readily extendable to quantum dots and color centers. Our work ushers in a new line of experiments that provide access to the coherent and nonlinear couplings of few emitters and few propagating photons.Efficient interaction of light and matter at the ultimate limit of single photons and single emitters is of great interest from a fundamental point of view and for emerging applications in quantum engineering.
