Optically induced transparency in a micro-cavity

Abstract

Electromagnetically induced transparency has the unique ability to optically control transparency windows with low light in atomic systems. However, its practical applications in quantum physics and information science are limited due to rigid experimental requirements. Here we demonstrate a new mechanism of optically induced transparency in a micro-cavity by introducing a four-wave mixing gain to nonlinearly couple two separated resonances of the micro-cavity in an ambient environment. A signature Fano-like resonance was observed owing to the nonlinear interference of the two coupled resonances. Moreover, we show that the unidirectional gain of the four-wave mixing can lead to the remarkable effect of non-reciprocal transmission at the transparency windows. Optically induced transparency may offer a unique platform for a compact, integrated solution to all-optical and quantum information.

Modeling and Simulation of the Intrinsic Function of a Photonic Switch

“…Removing the "on" SLD source and applying the "off " SLD source introduces an optical transparency [19,20] into the combined drop output spectrum and this is shown in Figure 3 by the blue spectrum. The blue spectrum exhibits a minimum at a resonant wavelength of 1.5487 µm.…”

Induced Transparency with Optical Cavities

“…Experimental demonstration and theorical predication in Figure 12b show the expected transparency, asymmetric Fano-like lineshapes when detuning the pump, and Figure 12c verified the nonreciprocal feature of OIT, which is attributed to the unidirectional FWM gain. [206,207] There is much similarity between OIT and aforementioned BSIT, with OIT using FWM gain, the latter Brillouin scattering gain and both nonreciprocal. Nonmagnetic optical isolation and quantum information processing may be extended from the OIT mechanism.…”
