Magnetic field-induced spectroscopy of strongly forbidden optical transitions

March 3, 2006
Author(s)
Alexey Taychenachev, V Yudin, Christopher W. Oates, C Hoyt, Zeb Barber, Leo W. Hollberg
We propose a method that uses a static magnetic field to enable direct optical excitation of forbidden electric dipole transitions that are otherwise prohibitively weak. The method is based on mixing of atomic states by a static magnetic field. The method

Precision Wavelength Metrology with a Fourier Transform Spectrometer

June 1, 2003
Author(s)
D. Veza, Marc L. Salit, John C. Travis, Craig J. Sansonetti
We have investigated the intrinsic accuracy of the optical frequency scale in spectra acquired by a Fourier Transform Spectrometer (FTS). The uncalibrated accuracy of the FTS optical frequency axis is about 1 part in 10 5. This uncertainty can be reduced

Noise Parameter Uncertainties from Monte Carlo Simulations

November 8, 2001
Author(s)
James P. Randa, Wojciech Wiatr
We present results for uncertainties in noise-parameter measurements, obtained using a Monte Carlo simulation of the measurements. Sets of data were generated to simulate measurements on a low-noise amplifier, with given uncertainties in the underlying

A Feature-Based Inspection and Machining System

August 1, 2001
Author(s)
Thomas R. Kramer, Hui-Min Huang, Elena R. Messina, Frederick M. Proctor, Harry A. Scott
This paper describes an architecture for a system for machining and inspectingmechanical piece parts and an implementation of it called the Feature-BasedInspection and Control System (FBICS). In FBICS, the controller of a machiningcenter or coordinate

Distribution of Link Distances in a Wireless Network

March 1, 2001
Author(s)
Leonard E. Miller
The probability distribution is found for the link distance between two randomly positioned mobile radios for two representative deployment scenarios: (1) the mobile locations are uniformly distributed over a rectangular area and (2) the x and y

Four-Port Microwave Measurement System Speeds On-Wafer Calibration and Test

March 1, 2001
Author(s)
Dave K. Walker, Dylan F. Williams, Allen Padilla, Uwe Arz, Hartmut Grabinski
A multiport measurement system comprising a coaxial switch network and comprehensive freeware package extends the capabilities of a user's two-port automatic network analyzer and probe station to three-and four-port measurements. The coaxial switch matrix
