51. The Next Generation of Laser Radiometry at NIST
Topic: Optoelectronics
Published: 2/27/2006
Authors: John H Lehman, Christopher L Cromer, Marla L Dowell
Abstract: High accuracy laser radiometry is on the verge of significant improvements just as new laser technologies are evolving. Our present tasks are directed toward anticipating and meeting the measurement needs in two areas; higher power and shorter wavele ...

52. Application of carbon nanotube coatings for laser measurements
Topic: Optoelectronics
Published: 10/17/2005
Authors: John H Lehman, Paul Rice, Natalia Varaksa, Chaiwat Engtrakul, Anne Dillon
Abstract: We have demonstrated coatings based on carbon nanotubes (CNTs) on a variety of detector platforms for laser power and energy measurement standards. These coatings must be resistant to damage and aging while maintaining desirable optical and thermal p ...

53. Precision Metrology for Fiber-Amplifier Noise Figure Traceable to a RIN Standard
Topic: Optoelectronics
Published: 8/16/2004
Authors: Gregory E Obarski, Paul D Hale
Abstract: We developed high-precision metrology for fiber-amplifier noise figure based on application of a relative intensity noise (RIN) standard to the RIN subtraction method. Calibration of a RIN/noise figure measurement system using the standard yields a t ...

54. Transfer function approach to the experimental determination of mode transfer matrices
Topic: Optoelectronics
Published: 7/20/1990
Authors: Shao Yang, Igor Vayshenker, D. R. Hjelme, I. P. Januar, A. R. Mickelson
Abstract: An improved scheme for characterization of multimode fiber systems is investigated. Characterization with transfer matrices requires multiple measurements for each component. The transfer function approach herein investigated requires only a single l ...

55. Transfer function analysis of measured transfer matrices
Topic: Optoelectronics
Published: 8/1/1989
Authors: Shao Yang, Igor Vayshenker, A. R. Mickelson
Abstract: Measurements of mode transfer matrices of various multimode fiber optic connectors are presented. To analyze the accuracy and repeatability of such measurements, a theoretical framework which employs mode transmission functions is derived. It is sho ...

56. NBS SPECIAL PUBLICATION 720: Technical Digest Symposium on Optical Fiber Measurements, 1986
Series: Special Publication (NIST SP)
Report Number: 720
Topic: Optoelectronics
Published: 1/1/1986
Authors: Igor Vayshenker, D. R. Hjelme, A. R. Mickelson
Abstract: When designing a multimode fiber system (MFS) one should take into consideration the mode-dependent properties of the components of the system. Lack of a design tool for fiber-optics netowrks makes the problem more difficult. However, one can describ ...

57. A General Approach to Low noise Readout of Terahertz Imaging Arrays
Topic: Optoelectronics
Published: Date unknown
Authors: Erich N Grossman, Jonathan D Chisum, Zoya Popovic
Abstract: This article describes the theory and design of an ultra-low noise electronic readout circuit for use with room temperature video-rate terahertz imaging arrays. First, the. noise characteristics of various imaging detectors,including low resistance b ...

58. Catalyst-free GaN Nanowires as Nanoscale Light Emitters
Topic: Optoelectronics
Published: Date unknown
Authors: Kristine A Bertness, Norman A Sanford, John B Schlager, Alexana Roshko, Todd E Harvey, Paul Timothy Blanchard, Matthew David Brubaker, Andrew M. Herrero, Aric Warner Sanders
Abstract: Catalyst-free growth of GaN nanowires with molecular beam epitaxy produces material of exceptionally high quality with long minority carrier lifetimes and low surface recombination velocity. The nanowires grow by thermodynamic driving forces that enh ...

59. Superconducting transition-edge sensors optimized for high-efficiency photon-number resolving detectors
Topic: Optoelectronics
Published: Date unknown
Authors: Adriana Eleni Lita, Brice Robert Calkins, Lenson Pellouchoud, Aaron J Miller, Sae Woo Nam
Abstract: Superconducting photon detectors have emerged as a powerful new option for detecting single photons. System detection efficiency that incorporates the quantum efficiency of the device and system losses is one of the most important single-photon detec ...

Topic: Optoelectronics
Published: Date unknown
Authors: Okan Esenturk, Joseph S Melinger
Abstract: We report the first direct comparison of relative carrier mobilities in semiconducting organic polymer films measured using non-contact optical pump terahertz probe spectroscopy to those reported in electrical device studies. Relative transient sign ...
