Low-Loss All-Optical Zeno Switch in a Microdisk Cavity Using EIT

Abstract

We present theoretical results of a low-loss all-optical switch based on electromagnetically induced transparency and the classical Zeno effect in a microdisk resonator. We show that a control beam can modify the atomic absorption of the evanescent field which suppresses the cavity field buildup and alters the path of a weak signal beam. We predict more than 35 dB of switching contrast with less than 0.1 dB loss using just 2 micro-Watts of control-beam power for signal beams with less than single photon intensities inside the cavity.

Updated with new references, corrected Eq 2a, and added introductory text. 7 pages, 5 figures, 3 tables
