In contrast to popular belief, it is possible to simulate a relativistic Dirac equation in classical paraxial optical waveguide arrays. Here, we present various simulations of relativistic phenomena in different structures, including so-called “optical graphene”.
The talk presents the initial evolution of the heterostructure idea in the years 1954–1963. Originally proposed for improving bipolar transistors, heterostructures made it possible to achieve cw laser at room temperature.
With our recent development of novel frequency combs in the mid infrared and extreme ultraviolet, we have opened the door for sensitive and high-resolution spectroscopy in these spectral regions. I will report these advances.
We describe nonlinear and quantum interactions of photons in chip-scale nanostructures and photonic crystals, including slow-light four-wave-mixing, femtosecond solitons, cavity optomechanics, quantum electrodynamics and information processing.
The distinctive physics and properties of self assembled quantum dot material are discussed and demonstrated in InAs and InP dot systems with reference to laser and related device application.
We review recent experiments on the use of disordered photonic crystals for enhancing light-matter interaction. Coupling single quantum dots to Anderson-localized modes enables cavity quantum electrodynamics with random cavity modes.
Channel capacities measure the ultimate communication abilities of noisy channels. I discuss capacities for optical channels with Gaussian noise and show the capacity for quantum information has surprising aspects that could be probed experimentally.
I will present progress in ultrafast all-optical quantum switching. χ(3)-based devices can route entangled single photons without disturbing their quantum state [1], whereas χ(2)-based devices can, in principle, lead to dissipation-free quantum-optical Fredkin gates [2].
The solar industry has grown at an astonishingly high rate over the past decade. This growth has been both in what one could consider the “traditional” areas such as flat panel crystalline silicon arrays, as well as in “new” technologies such as thin film CdTe arrays on glass. We will review some of the major discoveries of the past and trace how the industry came to be where it is today. We will...
Integration of localized molecular spectroscopy into standard medical imaging instrumentation has been slow in developing, yet today there have been major developments which make it achievable on a routine basis. Perhaps the most striking thing about optical imaging is the incredibly wide range of technologies available, and the correspondingly large range of resolutions in which they target, from...
We discuss the photoluminescence response mechanisms of III-nitride nanowires and nanowire heterostructures to adsorption of different gases or for pH detection in electrolytes as well as their application in novel optical sensor systems.
We present recent advances, combining novel laser technologies and spectroscopic methods, for high-sensitivity detection of volatile organic compounds within the context of the formation of secondary pollutants that affect human health and climate.
Quantitative phase imaging, i.e., measuring the map of pathlength shifts due to the specimen of interest, has been developing rapidly over the past decade. The main methods and exciting applications to biomedicine will be reviewed.
After an introduction on silicon photonics and on third-order nonlinear effects, the nonlinear properties of silicon are discussed. Then progress on nonlinear optics in silicon is reviewed both for telecom and mid IR bands.
