Functionalization of Conjugated Polymer Nanoparticles for Fluorescence Photomodulation.

The emission of conjugated polymer nanoparticles (CPNs or Pdots) is often tailored for specific uses by functionalizing CPNs with dyes that act as fluorescence resonance energy transfer (FRET) acceptors. A number of dye functionalization methods for CPNs have been developed, ranging from simple non-covalent doping to covalent attachment. We seek to develop guidelines for when non-covalent doping is acceptable and when covalent attachment is necessary to achieve the desired result. We present results of CPNs...

Forced rotation of nanograting in glass by pulse-front tilted femtosecond laser direct writing.

Femtosecond pulse laser with tilted intensity front demonstrates the capability of rotating the writing of nanograting in glass in 3D space. Other than the light polarization, this phenomenon is also associated with the quill-writing effect, which depends on the correlation between the sample movement and the pulse front tilt. This is because a pondermotive force, perpendicular to the tilted intensity plane, can push the excited electron plasma forward towards the pulse front. This behavior further tilts th...


Fabrication of digital rainbow holograms and 3-D imaging using SEM based e-beam lithography.

Here we present an approach for creating full-color digital rainbow holograms based on mixing three basic colors. Much like in a color TV with three luminescent points per single screen pixel, each color pixel of initial image is presented by three (R, G, B) distinct diffractive gratings in a hologram structure. Change of either duty cycle or area of the gratings are used to provide proper R, G, B intensities. Special algorithms allow one to design rather complicated 3D images (that might even be replacing ...


Fluorescence correlation spectroscopy with visible-wavelength superconducting nanowire single-photon detector.

We present the first demonstration of fluorescence correlation spectroscopy (FCS) using superconducting nanowire single-photon detectors (SSPDs) which are free of afterpulses unlike the avalanche photodiode (APD). Multimode-fiber-coupled SSPDs with high system detection efficiency for visible wavelengths were developed and implemented in the FCS system. We performed FCS measurements for Rhodamine B and 6G as fluorescent samples, and found that autocorrelation functions obtained by the SSPDs showed a noise-f...


Fast focus estimation using frequency analysis in digital holography.

A novel fast frequency-based method to estimate the focus distance of digital hologram for a single object is proposed. The focus distance is computed by analyzing the distribution of intersections of smoothed-rays. The smoothed-rays are determined by the directions of energy flow which are computed from local spatial frequency spectrum based on the windowed Fourier transform. So our method uses only the intrinsic frequency information of the optical field on the hologram and therefore does not require any ...


Fano resonance of self-collimated beams in two-dimensional photonic crystals.

We report that the Fano resonance of self-collimated beams can be achieved in a two-dimensional photonic crystal by introducing a Fano resonator that is composed of zigzag line defects. An asymmetric Fano line shape in a transmission spectrum is generated by the interference between radiated light beams from the resonator and self-collimated beams that directly pass through the resonator without resonance. It is shown that the Fano profile increases in sharpness as the number of zigzag line defects increase...


Few-mode multi-element fiber amplifier for mode division multiplexing.

We experimentally demonstrate a few-moded cladding-pumped multi-element fiber amplifier, comprising 4 Er/Yb co-doped signal fibers and 1 multimode pump-delivery fiber all of which are drawn together in a common polymer coating, providing a total spatial path multiplicity of 12. An average WDM signal gain of 18.3 dB and differential modal gain of 1.1 dB were achieved in the spectral range of 1542-1560 nm.


Feature issue of digital holography and 3D imaging (DH) introduction.

The OSA Topical Meeting "Digital Holography and 3D Imaging (DH)," was held in Seattle, Washington, July 13-17, 2014. Feature issues based on the DH meeting series have been released by Applied Optics (AO) since 2007. This year Optics Express (OE) and AO jointly decided to have one such feature issue in each journal. The DH meeting will continue in the future, as expected, and the next meeting is scheduled to be held on 24 - 28 May 2015, in Shanghai Institute of Optics and Fine Mechanics, Shanghai, China.


Formation of ultrashort triangular pulses in optical fibers.

Specialty shape ultrashort optical pulses, and triangular pulses in particular, are of great interest in optical signal processing. Compact fiber-based techniques for producing the special pulse waveforms from Gaussian or secant pulses delivered by modern ultrafast lasers are in demand in telecommunications. Using the nonlinear Schrödinger equation in an extended form the transformation of ultrashort pulses in a fiber towards triangular shape is characterized by the misfit parameter under variety of incide...


False-positive lupus anticoagulant in patients receiving rivaroxaban: 24 h since the last dose are needed to exclude antiphospholipid syndrome.

Rivaroxaban, a direct factor Xa inhibitor, affects laboratory clotting tests. We report here 10 venous thromboembolism patients with false-positive lupus anticoagulant during rivaroxaban therapy. Two dilute Russell Viper Venom time (dRVVT)-based integrated assays, HemosIL dRVVT Screen/HemosIL dRVVT Confirm (Instrumentation Laboratory, LA1/LA2 (Siemens, Germany) and LA1/LA2 (Siemens, Marburg, Germany), showed that the patients were lupus anticoagulant-positive. Antiphospholipid antibodies were negative excep...

Foxk proteins repress the initiation of starvation-induced atrophy and autophagy programs.

Autophagy is the primary catabolic process triggered in response to starvation. Although autophagic regulation within the cytosolic compartment is well established, it is becoming clear that nuclear events also regulate the induction or repression of autophagy. Nevertheless, a thorough understanding of the mechanisms by which sequence-specific transcription factors modulate expression of genes required for autophagy is lacking. Here, we identify Foxk proteins (Foxk1 and Foxk2) as transcriptional repressors ...

Frequency response and bandwidth in low-numerical-aperture step-index plastic optical fibers.

By experimental measurement and from a numerical solution to the time-dependent power flow equation, the frequency response, bandwidth, mode coupling, and mode-dependent attenuation are determined for a low-numerical-aperture (NA) plastic optical fiber. Frequency response and bandwidth are specified as a function of fiber length. Numerical results are verified against experimental measurements. Mode coupling and modal attenuation are found to differ substantially between two fiber varieties of the same type...
