Photonic memory using engineered modes of a nanophotonic waveguide

Presenting Author: Tyler Thurtell, Miami University

An atomic ensemble of three-level atoms can store a photon state if the control field is manipulated properly. A limit is placed on the storage fidelity by spontaneous emission. The spontaneous emission rate of an ensemble of atoms can be modified by super and sub-radiance. It has recently been shown that selectively radiant states exist for which some modes are sub-radiant and others are super-radiant, that such states can be prepared in three level atoms undergoing EIT coupled to a nanofiber and that such states may exponentially improve storage fidelity. We use the Quantum Toolbox in Python(QuTIP) to integrate the master equation describing these systems and produce a numerical model of these results. The emission type is controlled via modification of the collapse operators. We then consider a variety of nanophotonic waveguides and fibers.
