EIT in Microcavities: Towards Ultra-Low Power Optical Nonlinearities

Abstract

With our detailed theoretical studies, we show how inserting materials that support electro-magnetically induced transparency into microcavities enables design of microcavities with extraordinarily long lifetimes, and enables all-optical signal processing at single photon energy levels.

Electromagnetically induced transparency in microcavities

Using detailed numerical simulations, and analytical theory, we study properties of micro-cavities which incorporate materials that exhibit Electro-magnetically Induced Transparency (EIT) or Ultra Slow Light (USL). We find that such systems, while being miniature in size (order wavelength), and integrable, can have some outstanding properties. In particular, they could have lifetimes orders of magnitude longer than other existing systems, and could exhibit non-linear all-optical switching at single photon power levels. Potential applications include miniature atomic clocks, and all-optical quantum information processing.

New windows of opportunity for all-optical information processing: spatial solitons, EIT in microcavities, etc.

Marin Soljacic A, Elefterios Lidorikis, John D. Joannopoulos +4 more

We present two potentially interesting new venues in all-optical signal processing. First, we demonstrate experimentally that collisions between vector (Manakov-like) solitons involve energy exchange; this feature could be explored for all-optical signal processing. Second, our detailed theoretical studies show how inserting materials that support electro-magnetically induced transparency into microcavities enables design of microcavities with extraordinarily long lifetimes, and enables all-optical signal processing at single photon power levels.

Study of optical microcavities with electromagnetically induced transparency for developing new photonic devices

Jorge L. Arce-Diego, Félix Fanjul-Vélez, D. Pereda-Cubián +1 more

All optical devices based on nonlinear effects that use low-level power pumping acquire a great importance in optical communications systems and photonic processing. These optical devices can be implemented by means of different structures and materials. For instance, Fabry-Perot vertical microcavities, whispering gallery based microcavities or hybrid system of photonic crystal microcavities can improve their performance and so make possible a real implementation. In this research work we review the properties of optical media with three-level systems in which electromagnetically induced transparency has been induced. We analyse the effect of including such kind of material in an optical microcavity of the order of wavelenghts. Transmission properties like as the quality factor, the peak of transmission, the power of the coupling field in these microcavities with very small volume and very high non-linear Kerr coefficients will be analysed. Their application for developing new all-optical photonic devices for the next generation of all-optical networks, optical packets switching networks, and quantum information processing will be presented.
