Welcome to San Francisco, California and the 25th IEEE Photonics Conference (previously known as the IEEE LEOS Annual Meeting). Following in the path of previous successful meetings, this year's conference features an extensive range of technical activities in addition to some unique events.
Demonstration of high-speed second harmonic holographic microscopic imaging of biological specimens up to 1500 volumes per second with signal-to-noise analysis and 3D particle tracking. Additionally, SHG holography phase-shifted reconstruction and polarization-resolved imaging are developed.
We report photovoltaic infrared detectors based on graded-barrier asymmetric heterostructures. Detectors with a single period structure showed room temperature operation with a zero-response threshold of ∼4 µm, and a comparable detectivity to 30-period photoconductive split-off detectors reported previously. An additional long-wavelength response peak of up to 8 µm was also observed when the operating...
We report on the realization of a GaAs type-I quantum dot solar cell with a record 29.9 mA/cm2 short circuit current density and we compare it to a reference bulk GaAs solar cell.
We present a wideband tunable optical cavity based on electrostatic actuation. Over 60nm shift in wavelength is achieved by applying less than 1 Volt corresponds to a mechanical displacement of 30nm.
We propose and experimentally demonstrate a new approach to the design of Photonic Crystal cavities. Rather than simply maximizing the design Q-factor, we take the effects of disorder into account, and develop a design that provides superior Q factors in the presence of disorder relative to existing designs.
We demonstrate a CMOS-controlled color-tunable micro-display system based on a micro-light emitting diode array made from one InGaN epitaxial structure. This system can also be used for high speed optical data transmission.
Plasmonic color filters and polarizers were produced using nanotransfer printing to create aluminium nanostructures, as small as 75nm, on a polycarbonate sheet measuring 10mm × 12mm. Plasmonic filters showed good agreement with simulations.
The quantum Langevin analysis for QCLs show that coupling strength and dephasing rate strongly affect the linewidth of THz QCLs in incoherent resonant-tunneling transport regime, but induce insignificant influence for mid-infrared QCLs due to strong coupling.
Terahertz waves (0.1–10 THz) have promising applications in several fields including spectroscopy, imaging, and wireless communication [1]. However, several components still need to be developed for THz waves: a source, detector, filter, absorber, and modulator. In fact, an effective method for controlling THz waves has not been established yet.
We demonstrate a novel 20-GSample/s burst-mode CDR circuit featuring instantaneous (0-bit) phase acquisition with BER<10−10 for any phase step (2π rad) between successive bursts. Our design incorporates injection-locking and space sampling for clock phase recovery/alignment.
Recently, the Fano resonance, known from atomic physics, has been employed for a wide variety of nanophotonic structures, such as quantum dots, photonic crystals (PCs), plasmonics, and metamaterials. [1, 2] With modal dispersion engineering, Fano filters and reflectors can all be realized in single-layer dielectric PC structures. [3–5] We report here ultra-compact surface-normal high-Q Fano resonance...
Full visible range covering InP/ZnS core-shell nanocrystals with high photometric performance have been prepared. Making use of these nanocrystals, we demonstrate a white quantum dot LED with a high color rendering index of 91.
We discuss the motivations and progress made towards the development of a unified control architecture based on Software Defined Networking (SDN) for packet and circuit switched networks.
Reported here are optical fibers exhibiting significant longitudinal changes in optical properties over short lengths. The Brillouin gain is found to decrease by over 6 dB relative to a standard optical fiber as a result
A highly temperature sensitive directional coupler is demonstrated experimentally by selectively filling nematic liquid crystal into a single void of the photonic crystal fiber. The temperature response of the device exhibits good linearity.
We investigate the open problem of optimal home circuit (HC) grouping in LOBS-HC rings, and formulate it using Integer Linear Programming (ILP). Numerical results show that our ILP solutions require minimum wavelengths.
SiO2 coatings on the blue emitting halophosphate phosphors were studied. Luminescence output and moisture stability of micron-sized blue emitting halophosphate phosphors are 15–20% improved by SiO2 coatings.
