Light Trapping with Silicon Light Funnel Arrays
Silicon light funnels are three-dimensional subwavelength structures in the shape of inverted cones with respect to the incoming illumination. Light funnel (LF) arrays can serve as efficient absorbing layers on account of their light trapping capabilities, which are associated with the presence of high-density complex Mie modes. Specifically, light funnel arrays exhibit broadband absorption enh...
متن کاملNeural Network Tools For Stellar Light Prediction
This paper presents a comparative study of state-of-the-art neurocomputing methods applied to several benchmark time series, including the white dwarf light curve. The goal is to determine which of the predictive models work best for data from natural sources. The emphasis is on using a unified methodology for selection of the best architectures among those used for comparison. The specific arc...
متن کاملA Concept for an STJ-based Spectrograph
We describe a multi-order spectrograph concept suitable for 8m-class telescopes, using the intrinsic spectral resolution of Superconducting Tunneling Junction detectors to sort the spectral orders. The spectrograph works at low orders, 1–5 or 1–6, and provides spectral coverage with a resolving power of R≃ 8000 from the atmospheric cutoff at 320 nm to the long wavelength end of the infrared H o...
متن کاملRectangular Ion Funnel: A New Ion Funnel Interface for Structures for Lossless Ion Manipulations
Structures for lossless ion manipulations (SLIM) have recently demonstrated the ability for near lossless ion focusing, transfer, and trapping in subatmospheric pressure regions. While lossless ion manipulations are advantageously applied to the applications of ion mobility separations and gas phase reactions, ion introduction through ring electrode ion funnels or more conventional ion optics t...
متن کاملThe Spectrograph
JILA Fellow John Hall will deliver the 2006 Richard C. Lord Lecture on May 2, on “Optical clocks, combs and coherence: defining and measuring optical frequency.” Born in 1934 in Denver, Hall is an alumnus of the Carnegie Institute of Technology, where he received B.S., M.S. and Ph.D. degrees. He conducted postdoctoral studies at the Department of Commerce’s National Bureau of Standards, now cal...
