  • Enright R.
  • Michael A. Morris
  • Parvaneh Mokarian-Tabari

Superhydrophobic surfaces in the so-called Cassie or non-wetting state display extreme wetting behavior through a combination of surface texture and hydrophobic surface chemistry that can cause water droplets to roll or bounce off, carrying away dust particle and other contaminants in the process. Potential applications for these surfaces range from ...

MULTI-VIEW IN LENSLESS COMPRESSIVE IMAGING

Quadrature and number fluctuations produced by parametric devices driven by pulsed pumps

  • Marhic M.
  • Mckinstrie C.

Two sets of formulas are derived for the field-quadrature and photon-number fluctu- ations (variances and correlations) produced by parametric amplifiers and frequency convertors that are driven by pulsed pumps and act on pulsed signals. The first set is based on the Green functions for the underlying parametric processes, whereas the ...

The gain compression coefficient was evaluated by frequency modulation/amplitude modulation technique in a distributed feedback InAs/InGaAs quantum dot laser. Strong dependence of the gain compression coefficient on the output power was found. Analysis of the gain compression in frameworks of the modified well-barrier hole burning model reveals that the gain ...

Parity Check Encoded QPSK for Rate Adaptation in Coherent DSP-Based Receivers

  • Kaneda N.
  • Lee S.
  • Pfau T.

An ultra-short rate-1/2 parity check code is used to switch the net data rate of a coherent QPSK transmission system to the equivalent of a BPSK system. Simulation and experimental comparison of parity check encoded (PC)-QPSK and BPSK show an improvement in receiver sensitivity of 0.8 dB at the soft-FEC ...
