The coupling of a sensor to its environment leads to dissipation which, according to the fluctuation-dissipation theorem, makes the output of the sensor noisy. This minimum amount of noise places a lower bound on the magnitude of the perturbation that a linear sensor can detect within a certain time. In this talk, I will discuss how noise can be turned into an advantage for sensing when using a nonlinear photonic resonator. I will show how the speed of such a sensor increases with the noise strength, while its sensitivity is optimum for a finite value of the noise strength.
Said Rodriguez leads the Interacting Photons group at the Center for Nanophotonics in AMOLF. Said got his PhD (Cum Laude) at TU/Eindhoven, having worked in the former AMOLF/Philips group J. Gómez Rivas. Next he worked at Center for Nanosciences and Nanotechnology (France) as a Marie-Curie fellow with J. Bloch and A. Amo. Said’s research interests include nanophotonics, nonlinear & quantum optics, and stochastic systems.
