Simultaneous 3D-flow field and compliant wall measurements in an abdominal aortic aneurysm flow using scanning-PTV
index matching scanning particle tracking velocimetry flow phantom
2015/8/25
We combine well established particle tracking with wall surface measurements using tomographic scanning and present results for the non-stationary 4D - flow field within an abdominal aortic aneurysm (...
Noise Figure Measurements in Phase-Insensitive and Phase-Sensitive Fiber Parametric Amplifier Cascade
Fiber optics amplifiers and oscillators Nonlinear optics four-wave mixing
2015/6/10
By cascading two non-degenerate inline fiber-optic parametric amplifiers, we observe NF ~2dB (beating phase-insensitive quantum limit) at 16-dB gain for the second (phase-sensitive)stage after subtrac...
First 80-Gb/s and 160-Gb/s Wavelength-Converted Data Stream Measurements in a Silicon Waveguide
Wavelength conversion devices Nonlinear optics four-wave mixing
2015/6/10
Data fidelity is inspected for the first time for wavelength-converted RZ TDM 80- and 160-Gb/s data using four-wave mixing in a silicon waveguide. Open eye diagrams and error-free operation is shown f...
Continuous,Real-Time,Full-Field Waveform Measurements via Spectral Slicing and Parallel Digital Coherent Detection
Homodyning Phase measurement Ultrafast measurements
2015/6/10
Single-shot, amplitude and phase characterization of 160-GHz bandwidth optical wave-forms with 2-μs record lengths using a bandwidth- and time-record scalable technique based on parallelized balanced ...
Intra-Channel Chromatic Dispersion Measurements with Live Neighboring Signals in a Long Haul DWDM System
Optical communications Networks wavelength routing Fiber measurement
2015/6/5
A novel four-tone probe signal is used to measure end-to-end residual chromatic dispersion in single 50-GHz DWDM channels of a long-haul ROADM network while transmitting more than 30 live signals in n...
Determination of Localized Loss in Cabled Fiber Using OTDR Measurements of Relative Mode Field Diameter
Fiber Characterization Fiber Measurements
2015/6/5
We demonstrate enhanced sensitivity of a commercial OTDR by employing novel bidirectional analysis techniques. The method is applicable to measurements of cabled fiber where fluctuations in local mode...
In-Service Chromatic Dispersion and Pass-Band Shape Measurements for Light Path with Modulated ASE Source
Networks wavelength routing Fiber measurement
2015/6/5
A tunable modulated broadband source and narrow-bandwidth filter are used to measure chromatic dispersion, group-delay ripple, and pass-band shape of DWDM-network light paths. This new method is simpl...
Measurements of the Birefringence and Verdet Constant in an Air-Core Fiber
Birefringence Verdet Constant Air-Core Fiber
2015/8/10
In order to determine the Verdet constant of an aircore photonic bandgap fiber (PBF), the birefringence of the fiber needs to be accurately known. We used two methods to measure the linear...
Thermal Diffusivity Measurements of Metals and Alloys by Making Use of the Phase Shift of Laser-Induced Thermoelastic Wave
Thermal diffusivity measurement Thermo elastic wave CO2 laser
2009/6/8
This paper describes a method of obtaining the thermal diffusivity of a metal sample of known thickness. By irradiating an intensity-modulated laser beam of 8 W to the sample at power density of 1.5 ×...
Sensitivity of Interferometric OSNR Measurements Techniques to the Variation in Signal Extinction Ratio
Sensitivity Interferometric OSNR Measurements Techniques Variation Signal Extinction Ratio
2015/7/31
We discuss calibration requirements for interferometric OSNR measurements. We show that variation of 0.25dB in the signal extinction ratio could result in large errors in OSNR for 42.8Gb/s modulated s...
