- Abstract summary: A single quantum emitter can possess a very strong intrinsic nonlinearity, but its overall promise for nonlinear effects is hampered by the challenge of efficient coupling to incident photons.
We show that a single organic molecule acts as an extremely efficient nonlinear optical element in the strong coupling regime of cavity quantum electrodynamics.

- Abstract: A single quantum emitter can possess a very strong intrinsic nonlinearity,
but its overall promise for nonlinear effects is hampered by the challenge of
efficient coupling to incident photons. Common nonlinear optical materials, on
the other hand, are easy to couple to but are bulky, imposing a severe
limitation on the miniaturization of photonic systems. In this work, we show
that a single organic molecule acts as an extremely efficient nonlinear optical
element in the strong coupling regime of cavity quantum electrodynamics. We
report on single-photon sensitivity in nonlinear signal generation and
all-optical switching. Our work promotes the use of molecules for applications
such as integrated photonic circuits, operating at very low powers.
