Supercollimation is the propagation of light without diffraction using the properties of photonic crystals. We present the first experimental demonstration of supercollimation in a planar photonic crystal composed of nanoscale rods. Supercollimation was observed over distances of up to 1000 lattice periods.

    We propose an optofluidic based on two-dimensional (2D) rod-type silicon photonic crystal (PhC) waveguide that supports self-collimation effect over a large frequency and angle range without any defect or nano-scale variation in the PhC geometry. By analyzing the equi-frequency counter (EFC) of...

    We present a 3×3 surface-normal wavelength-selective crossbar using polymer-based volume holograms. A prototype device is demonstrated using the center wavelength of 775 nm and Δλ=10 nm. Employment of 1/4-pitch graded-index rod lenses reduces the required nine wavelengths to three...

    Abstract. A practical method for scatter and attenuation compensation was employed in thallium-201 myocardial single-photon emission tomography (SPET or ECT) with the triple-energy-window (TEW) technique and an iterative attenuation correction method by using a measured attenuation map. The map...

    Abstract. Fan-beam collimators offer a good balance between resolution and noise. The collimator response may be included in iterative reconstruction algorithms in order to improve single-photon emission tomography (SPET) resolution. To this end, accurate determination of the local region and...
