Book excerpt: This final progress report summarizes research efforts in two areas: cavity QED of quantum dots and electromagnetically induced transparency (EIT) in GaAs quantum wells. Cavity QED studies are based on the development of a composite nanocrystal-microsphere system, in which CdSe/ZnS core/shell nanocrystals couple to whispering gallery modes (WGMs) in a fused silica microsphere. The composite microcavity system can feature a Q-factor as high as 108 and a nanocrystal decoherence rate as small as 3 microneV (0.75 GHz), indicating that the composite system can in principle reach the strong coupling regime of cavity QED. EIT studies have exploited the use of Coulomb interactions between excitons to induce and manipulate exciton spin coherence and biexciton coherence. These studies have led to the first experimental demonstration of EIT in inter-band optical transitions in semiconductors in A-type, cascaded, and V-type three-level systems.

Available in PDF, EPUB and Kindle. Book excerpt: Confinement and manipulation of photons using microcavities have triggered intense research interest in both basic and applied physics for more than a decade. Prominent examples are whispering gallery microcavities which confine photons by means of continuous total internal reflection along a curved and smooth surface. The long photon lifetime, strong field confinement, and in-plane emission characteristics make them promising candidates for enhancing light-matter interactions on a chip. In this book, we will introduce different ultra-high-Q whispering gallery microcavities, and focus on their applications in enhancing light-matter interaction, such as ultralow-threshold microlasing, highly sensitive optical biosensing, nonlinear optics, cavity quantum electrodynamics and cavity optomechanics.

This book was released on 2012-12-06 with total page 600 pages. Available in PDF, EPUB and Kindle. Book excerpt: The control of optical modes in microcavities or in photonic bandgap (PBG) materials is coming of age! Although these ideas could have been developed some time ago, it is only recently that they have emerged, due to advances in both atomic physics and in fabrication techniques, be it on the high-quality dielectric mirrors required for high-finesse Fabry Perot resonators or in semiconductor multilayer deposition methods. Initially the principles of quantum electro-dynamics (QED) were demonstrated in elegant atomic physics experiments. Now solid-state implementations are being investigated, with several subtle differences from the atomic case such as those due to their continuum of electronic states or the near Boson nature of their elementary excitations, the exciton. Research into quantum optics brings us ever newer concepts with potential to improve system performance such as photon squeezing, quantum cryptography, reversible taps, photonic de Broglie waves and quantum computers. The possibility of implementing these ideas with solid-state systems gives us hope that some could indeed find their way to the market, demonstrating the continuing importance of basic research for applications, be it in a somewhat more focused way than in earlier times for funding.

Download or read book High Q Microcavities as Multifunctional Elements for Chip scale Nonlinear and Quantum Optics written by Steven Daniel Rogers and published by . This book was released on 2019 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Optical microcavities greatly enhance the strength of light-matter interactions by confining optical modes to persistently circulate within a small volume of the device material. The utility of these systems is evidenced by their implementation in a wide variety of optical applications and fundamental studies. This dissertation focuses on the development of optical microresonators in the silicon-on-insulator platform for their application in nonlinear and quantum optics. Single-crystalline silicon microresonators are particularly well-suited for integrated nonlinear optical applications, due to their large refractive indices, large Kerr nonlinearities, high quality factor whispering-gallery modes, and narrowband Raman spectra. Furthermore, nonlinear parametric processes in silicon can be harnessed to create chip-scale quantum states of light with excellent characteristics. Moreover, the cavity-enhancement enables the generation of photon pairs with high purity and narrow spectral linewidth, as well as control over their spectro-temporal properties. Depending on the application, the photonic quantum states can be utilized as a source of entanglement or heralded to provide single photons. We elucidate the multifunctional nature of optical microresonators by investigating the creation of entangled photon pairs, heralded single photons, and indistinguishable twin photons within these devices. In each of these domains, the produced photonic quantum states are characterized and shown to exhibit features that make them best in class. Additionally, we demonstrate a new technique which can be universally applied for dispersion compensation in microresonator-based optical parametric processes. By spatially modulating the microresonator boundary, we show that individual cavity resonances can be targeted and frequency shifted to enable parametric generation. Finally, we propose and demonstrate a powerful tool for quantum optics, which is based on the creation and coherent conversion of photonic quantum states between coupled electromagnetic cavity modes. The modal coupling introduces new creation pathways to a nonlinear optical process within the device, which then quantum mechanically interfere to drive the system between states in the time domain. The coherent conversion entangles the biphotons between propagation pathways, leading to cyclically evolving path-entanglement and the manifestation of coherent oscillations in second-order temporal correlations. In turn, by tuning properties of the cavity, we are able to intrinsically manipulate the generated quantum states and their entanglement properties for the first time in a photon pair source. It is envisioned that such systems will open a route to exotic multi-photon states and higher dimensional entanglement."--Pages xi-xii.
