EIT IN HOLLOW-CORE FIBERS FOR OPTICAL COMMUNICATIONS DEVICES

Abstract

We developed an experimental setup for electromagnetically induced transparency able to manufacture microcells, suitable for optical fiber communications technology. A hollow-core photonic crystal fiber (HC-PCF) is filled with acetylene, to work in the 1500 nm telecommunications window. We used a HC-PCF with the mode-field diameter compatible with standard single-mode fibers, with the purpose of achieving low-loss splicing and enabling us to work at low pumping powers. This allows to induce a narrow transparency window, which can be spectrally adjusted and dynamically controlled. (c) 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:348-352, 2015
