This tutorial covers recent progress in the design of high-performance light emitting diodes with unusual sizes, shapes and forms. Applications range from large-area, flexible light sources for general illumination to cellular-scale, injectable systems for biomedicine.This tutorial covers recent progress in the design of high-performance light emitting diodes with unusual sizes, shapes and forms....
We present an experimental demonstration of an optical switch operating in the quantum regime, consisting of a single trapped atom near a nanoscale photonic crystal cavity.
I will review our progress on developing clinical and animal (mice) cellular resolution in vivo retinal imaging modalities. Example applications of these technologies to in vivo studies of microscopic retinal morphology will be presented.
We present the ability of OCT microangiography to visualize tissue blood flow at capillary level for a variety of biomedical applications, some of which (along with the OCT basics and the enabling technologies) will be highlighted
We assess the evolution of the optofluidics during the last decade. We will contrast the progress actually made with the expectations from 10 years ago and highlight some of the unexpected developments that have occurred.
This tutorial provides an introduction to the current state-of-the-art, the challenges and the prospects of achieving quantum optical control over nano-, micro- and macro-mechanical devices, i.e. quantum optomechanics.
This tutorial provides an overview of the basic physical mechanisms of supercontinuum generation. Recent progress in the field and novel physics linked to recently discovered soliton dynamics including optical rogue waves will be reviewed.
Transmission and reflection properties, anisotropy, chirality, optical nonlinearity and luminescent of metamaterials can be controlled at will using dynamic nanostructures reconfigurable with electromagnetic forces or by exploiting structured illumination with coherent light.
Newly discovered 2D semiconductors offer a platform to investigate valley excitons at the two dimensional limit. Here, we present optoelectronic control of valley exciton polarization and coherence, and their device applications in monolayer limit.
Optofluidics promises devices and systems in which both optical and fluidic components are integrated on the same chip. We will review progress in this field to date and present an outlook on future opportunities.
We show we can monitor blood vessel permeability, myelin degeneration and microglial activity with video rate microscopy. Advanced fiber optic tools are shown to permit control of activity in the spinal cord.
The nitrogen-vacancy center in diamond is a promising candidate to realize quantum networks. We create multi-qubit nodes of nuclear spins in the environment and couple these nodes together by entangling remote nitrogen-vacancy centers through photons.
The use of ultrafast laser writing for fabricating advanced 3D waveguide components is presented and demonstrated. Couplers for space division multiplexing allowing beyond Shannon limit spectral efficiency, and 3D hybrid integration capabilities are discussed.
A novel application of chirped dielectric mirrors for narrow beam focalization is proposed and demonstrated numerically and experimentally. Analogy to temporal dispersion compensation by chirped dielectric mirrors is discussed.
Holmium-doped ZBLAN fiber has proven to be an efficient high gain material in the 1.2 µm region. In this paper, single-mode fiber lasers and amplifiers at 1178 nm, 1190 nm, and 1200 nm are reported. Over 2 watts of continuous wave output power was achieved with a 10-cm long gain fiber.
This is the first time that significant Stokes output power of 0.88 W at 990 nm has been achieved using a three-level fundamental transition (quasi-cw Nd:YLF laser) with stimulated Raman scattering in a KGW crystal.
We experimentally demonstrate the RF photonics filter using optical tapped delay line based on an optical frequency comb and a PPLN waveguide as the multiplexer. RF filters with variable bandwidth, shape and center-frequency are implemented.
We demonstrate stimulated polariton emission at room temperature in a dielectric microcavity embedded with ZnO nanoparticles. The polariton lifetime is also shown to decrease drastically above the stimulated emission threshold.
We present a gain-switched-diode-seeded 1034.5-nm master oscillator power amplifier, employing direct amplification through standard commercial Yb3+-doped fibres to generate 15.6µJ-pulse-energy, 126kW-peak-power, picosecond pulses with 3dB spectral bandwidth of 0.87nm.
