Induced Transparency

By mapping photons into the sample of cuprous oxide with Rydberg excitons, it is possible to obtain a significant optical phase shift due to third-order cross-Kerr nonlinearities realized under the conditions of electromagnetically induced transparency. The optimum conditions for observation of the phase shift over π in Rydberg excitons media are examined. A discussion of the application of the cross-phase modulations in the field of all-optical quantum information processing in solid-state systems is presented.

A reconfigurable metamaterial analog electromagnetically-induced-transparency-like (EIT-like) effect is theoretically and numerically demonstrated in this paper. The unit cell is composed of a stimulated circular loop element and an unstimulated arc slot element, which are both constructed by semiconductor. The interaction between the two elements of the unit cell leads to a transparency window, resembling a special quantum optical phenomenon as electromagnetic (EM) induced transparency. The proposed designs can realize a continuously tunable EIT-like effect in a broad frequency range from 2.2 GHz to 3.6 GHz by changing the arc slot angle, while the number of EIT-like transmission windows can be configured by increasing the number of arc slots. This scheme which is constructed by solid state plasma (SSP) metamaterial provides an alternative way to realize the tunable plasmonic sensing and make new kinds of reconfigurable devices.
