The excitonic ground state in a quantum dot shows a size- and shape-dependent two-fold splitting due to exchange interaction. By tuning the splitting q-bit emission from the exciton or entangled photon emission from the exciton/biexciton cascade are possible.
Progress in the subject of cavity optomechanics will be described. Micromechanical oscillators to microwave rates, as well as progress directed towards cooling to the quantum ground state will be reviewed.
We discuss advances in quantum dots for nanophotonics and quantum information applications. After a historical review of research on quantum dots and their laser applications (i.e., quantum dot lasers), successful demonstration of temperature-stable quantum dot lasers and ultra-low threshold lasers with photonic crystal nanocavity are demonstrated. Moreover, recent progress in quantum dot information...
Optical performance monitoring might play a crucial role in enabling self-managed and reconfigurable high-performance optical networks. We will explore key motivating networking issues as well as potential monitoring techniques.
We demonstrate that optical activity for the zeroth-order transmitted light is extraordinarily enhanced in metal and dielectric planar chiral nanogratings by plasmon or waveguide resonance. This method can be used for THz applications.
We review the recent advances in optical injection-locked lasers, focusing on high resonance frequencies (> 100 GHz) and 3 dB bandwidth (> 80 GHz). Physical parameters governing the dynamic performance will be discussed.
Nanophotonics has recently achieved new dimensions in several aspects of nanoscience, such as nano-imaging, nano-analysis or even nano-manipulation of several kinds of samples ranging from semiconductors to biomolecules. The interaction volume between light and sample is classically restricted by so-called diffraction limit of light, which is about half of the wavelength of the probing light. We have...
Semiconductor nanowires have witnessed an explosion of interest in the last several years due to advances in synthesis and the unique thermal, optoelectronic, chemical, and mechanical properties of these materials. The potential applications of single-crystalline nanowires are truly impressive, including computational technology, communications, spectroscopic sensing, alternative energy, and the biological...
Dynamic single-mode (DSM) lasers ave been investigated extensively from early 1970s. In this paper, the fundamental properties and development of DSM lasers are reviewed.
We review the progress of synthesis, characterization and properties of III-V compound semiconductor nanowires and nanoneedles grown on lattice-mismatched substrates and a new family of optoelectronic devices based on high-contrast grating. There are intense interests in semiconductor structures with dimensions at the two ends of the nanometer regime. Materials with size on the order of a few nanometers,...
The manipulation of the quantum states of photons and its applications are reviewed. Topics include the super phase sensitivity using four entangled photons, and the fibre-microsphere systems toward photonic quantum information devices.
The talk discusses quantum dot micropillar cavities with electrical injection and quality factors in excess of 10.000. Weak and strong coupling effects and lasing are investigated. Challenges and the potential for device applications are discussed.
