Leonardo de Souza MenezesPhysicistResearch interestsThe experimental study of light-matter interaction in nanoscale, in afundamentally quantum level, is my main research interest. In order to do this, aNano Optics Laboratory is being implemented at the Physics Department of the FederalUniversity of Pernambuco. The idea is to concentrate on the investigation of modelsystems, through which it is expected to learn how to control the light-matter interaction,so that it becomes possible to study in detail the quantum effects which govern it.An isolated quantum light emitter, which can be a semiconductor quantum dot ordielectric nanocrystals containing rare-earth ions or organic molecules, isattached to the end of a sharp optical fiber tip. Using techniques borrowed from theScanning Near-field Optical Microscopy (SNOM) as a nanomanipulation tool, onemakes the nanoemitter interact with the eigenmodes of a dielectric microcavity (amicrosphere or a microtoroid made of silica), which present ultra-high quality factors,the so-called “whispering-gallery modes”.The microspherical resonators are produced by controllably melting ultra-puresilica, exposing it to the radiation of a CO 2 laser. Using a narrow linewidth tunablediode laser, it is possible to couple radiation to the cavity’s eigenmodes by using opticalcouplers, such as high refractive index prisms or optical fiber tapers. In this way, thedecay time of the electromagnetic field in these modes easily achieves a microsecond.Using a system like this, it may be possible to observe the “single quantum emitterlaser” phenomenon, among other effects related to cavity quantum electrodynamics inthe optical regime. In particular, the technological development of fiber taperingtechniques is interesting for nonlinear optical applications, like generation of white light,which has direct use in optical metrology.The use of SNOM probes is faced as a twofold capability tool: they may be usedas nanotools for manipulating particles which are hundreds of times smaller thenthe optical wavelength. More interestingly, however, is the fact that they allow one toprobe the electromagnetic field with a spatial resolution of tens of nanometers. By usingsuch a technique, it is possible to map a microcavity’s eigenmodes and to optimize thecoupling of radiation to one of them, at will.4

Leonardo de Souza MenezesPhysicistThe most attractive quantum emitters are the semiconductor nanocrystals. Due totheir nanometric dimensions, it is possible to reach the quantum confinement regime ofcharge carriers and quantum effects, like single-photon emission, may be observedeven at room temperature. The spectral properties of a semiconductor quantum dotmay also be manipulated in a very simple way, by choosing the materials from which itis made, by controlling the nanocrystal’s size (meaning to say, to control the strength ofthe quantum confinement effects) or even by applying an electric field around the regionwhere it is located. These quantum dots may also be used as sources of quantumradiation, through the generation of single photons on-demand due to the decay of anexciton. By exploiting the biexcitonic decay in these structures, one can obtain pair ofentangled photons, which may very useful for transmitting and processing quantuminformation.It is also a research interest to perform linear and nonlinear laser spectroscopiesof isolated nanoscopic particles (dielectric and metallic), by using laser scanningconfocal and near-field microscopy techniques.5
