1. Analysis of shot noise in the detection of ultrashort optical pulse trains
Topic: Physics
Published: 5/31/2013
Authors: Franklyn J Quinlan, Tara Michele Fortier, Haifeng (Haifeng) Jiang, Scott A Diddams
Abstract: We present a frequency domain model of shot noise in the photodetection of ultrashort optical pulse trains using a time-varying analysis. Shot noise-limited photocurrent power spectral densities, signal-to-noise expressions, and shot noise spectral c ...

2. Modulated photocurrent spectroscopy of CdTe/CdS solar cells-equivalent circuit analysis
Topic: Physics
Published: 5/20/2013
Authors: Behrang H Hamadani, John F Roller, Kounavis Panagiotis, Nikolai B Zhitenev, David J Gundlach
Abstract: We have used the technique of photocurrent modulated spectroscopy to investigate the dynamic response of charge carrier transport in thin film CdTe/CdS solar cells as a function of light bias and temperature over a broad excitation frequency range. T ...

3. Photonic microwave generation with high-power photodiodes
Topic: Physics
Published: 5/14/2013
Authors: Tara Michele Fortier, Franklyn J Quinlan, Archita Hati, Craig W Nelson, Jennifer A. Taylor, Yang Fu, Joe Campbell, Scott A Diddams
Abstract: We utilize and characterize high-power, high-linearity modified uni-traveling carrier (MUTC) photodiodes for low-phase-noise photonic microwave generation based on optical frequency division. When illuminated with 980 nm picosecond pulses from a repe ...

5. Spin transport parameters in metallic multilayers determined by ferromagnetic resonance measurements of spin-pumping
Topic: Physics
Published: 4/19/2013
Authors: Carl T Boone, Hans Toya Nembach, Justin M Shaw, Thomas J Silva
Abstract: We measured the spin-transport in nonferromagnetic (NM) metallic multilayers from the contribution to damping due to spin pumping from a ferromagnetic Co^d90^Fe^d10^ thin film. The multilayer stack consisted of NM^d1^/NM^d2^/Co^d90^Fe^d10^(2 nm)/NM^d ...

6. A critical compilation of energy levels, spectral lines, and transition probabilities of singly ionized silver, Ag II
Series: Journal of Research (NIST JRES)
Report Number: 118.009
Topic: Physics
Published: 4/15/2013
Author: Alexander Kramida
Abstract: All available experimental measurements of the spectrum of the Ag+ ion are critically reviewed. Systematic shifts are removed from the measured wavelengths. The compiled list of critically evaluated wavelengths is used to derive a comprehensive l ...

7. Sympathetic Electromagnetically-Induced-Transparency Laser Cooling of Motional Modes in an Ion Chain
Topic: Physics
Published: 4/12/2013
Authors: Yiheng Lin, John P Gaebler, Ting Rei Tan, Ryan Steven Bowler, John D. Jost, Dietrich G Leibfried, David J Wineland
Abstract: We use electromagnetically-induced transparency (EIT) laser cooling to cool motional modes of a linear ion chain. As a demonstration, we apply EIT cooling on ^u24^Mg^u+^ ions to cool the axial modes of a ^u9^Be^u+^-^u24^Mg^u+^ ion pair and a ^u9^Be^u ...

8. Arbitrary waveform generator for quantum information processing with trapped ions
Topic: Physics
Published: 3/20/2013
Authors: Ryan Steven Bowler, Ulrich J. Warring, Joseph Wright Britton, J. M. Amini
Abstract: Ions confined in a multi-electrode trap design have been proposed as a possible basis for quantum information processing. This scheme involves transporting ions between spatially distinct locations using time varying electric potentials combined with ...

9. Exploiting shot noise correlations in the photodetection of ultrashort optical pulse trains
Topic: Physics
Published: 3/10/2013
Authors: Franklyn J Quinlan, Tara Michele Fortier, Haifeng (Haifeng) Jiang, Archita Hati, Craig W Nelson, Yang Fu, Joe Campbell, Scott A Diddams
Abstract: Photocurrent shot noise represents the fundamental quantum limit of amplitude, phase and timing measurements of optical signals. It is generally assumed that non-classical states of light must be employed to alter the standard, time-invariant shot no ...
