Fast induced transmission via a quadratic nonlinear interaction within a microcavity

Abstract

Summary form only given. The enhancement of the light and matter interaction that can be obtained in periodic structures such as 1D photonic crystals or Fabry-Perot microcavities might be best used when the interaction considered is nonlinear. It has been theoretically shown that changes in the effective index of refraction of a dielectric material leading to large changes in reflection or transmission, can be obtained in a periodic array of layers with a /spl chi//sup (3)/ nonlinearity, or in a microcavity filled with a quadratic nonlinear material. We have considered a 43 /spl mu/m thick KTiOPO/sub 4/ crystal sandwiched between two identical mirrors.

Summary form only given. We analytically discuss a nonlinear quadratic regime of second harmonic generation in an optical cavity: a beam at frequency /spl omega/ overlapped with a beam at frequency 2/spl omega/ are incident on the surface of a Fabry-Perot interferometer filled with a quadratic material.

Actively induced transmission via a quadratic nonlinear optical interaction in a potassium titanyl phosphate microcavity

Crina M. Cojocaru, Ramon A. Vilaseca, Jordi Martorell +3 more

We report an actively induced change in the transmission of a light pulse passing through a microcavity filled with a 40 μm thick nonlinear potassium titanyl phosphate crystal. This change was induced by an intense pulse at the frequency of the second harmonic of the original pulse. The magnitude of the change was measured to be 20%. The observed changes in transmission are shown to be in very good agreement with the numerical results from a model that considers the intrinsically fast second-order nonlinear interaction between both pulses within the nonlinear microcavity.

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.

Bistability of Nonlinear Fabry-Perot Cavity

Song Jun

The bistability of vertical microcavity MQW structure is studied using transfer matrix method.Calculation results show that it is much easier to produce bistable states when the material with higher refractive index is in the vicinity of the nonlinear dielectric (i.e.MQW structure).Curves of the reflective phase and reflectivity varying with the incident optical power of nonlinear Fabry-Perot cavity are also calculated.The effect of the number of the DBR periods on the bistability is analyzed.

Enhanced nonlinear optics in photonic-crystal microcavities

Jorge Bravo‐Abad, Alejandro W. Rodríguez, Peter A. Bermel +3 more

Focus Serial: Frontiers of Nonlinear Optics Nonlinear photonic-crystal microresonators offer unique fundamental ways of enhancing a variety of nonlinear optical processes. This enhancement improves the performance of nonlinear optical devices to such an extent that their corresponding operation powers and switching times are suitable for their implementation in realistic ultrafast integrated optical devices. Here, we review three different nonlinear optical phenomena that can be strongly enhanced in photonic crystal microcavities. First, we discuss a system in which this enhancement has been successfully demonstrated both theoretically and experimentally, namely, a photonic crystal cavity showing optical bistability properties. In this part, we also present the physical basis for this dramatic improvement with respect to the case of traditional nonlinear devices based on nonlinear Fabry-Perot etalons. Secondly, we show how nonlinear photonic crystal cavities can be also used to obtain complete second-harmonic frequency conversion at very low input powers. Finally, we demonstrate that the nonlinear susceptibility of materials can be strongly modified via the so-called Purcell effect, present in the resonant cavities under study.

Optical bistability and signal amplification in a semiconductor crystal: applications of new low-power nonlinear effects in InSb

David A. B. Miller, Stanley Desmond Smith, A.M. Johnston

We report the observation of optical stability for a plane parallel semiconductor crystal which forms a Fabry-Perot interferometer using only the natural reflectivity of its surfaces. Nonlinear transmission is observed for cw laser intensities above ∼ 100 W/cm2 for radiation at 1895 cm−1 near the energy gap of InSb at 5 K. The effect is interpreted in terms of a very large intensity-dependent refractive index giving a 5λ/2 optical thickness change for an intensity of ∼2 kW/cm2. Clear bistability is seen in fifth-order interference, the first such observation above first order in an intrinsic, one-element system, in addition to regions exhibiting signal amplification. The same crystal also shows strong modulation of the transmission of one laser beam induced by a second, with real signal gain, thus demonstrating an ’’optical transistor.’’
