A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

This proposal is for the development of a technology apparatus which can dynamically synthesize a mechanical fingerprint pattern, from an electronic image or from a computer-generated artificial pattern, onto a 2-dimensional pliable surface whose surface height is modulated by protrusions in the z-axis direction. When mechanically applied to a fingerprint sensor-under-test, the synthesized modulat ...

Conversion of highly stable optical clocks into electrical clocks through photodetection introduces excess phase noise and degrades the frequency stability by two to three orders of magnitude.

Conversion of highly stable optical clocks into electrical clocks through photodetection introduces excess phase noise, thereby degrading the frequency stability. This noise is primarily generated due to the conversion of optical intensity noise into electrical phase noise by photodiode¿s non-linearity, specifically power-to-phase conversion. During Phase I, Discovery developed dual photodiodes h ...

The NIST patented six-degree of freedom micropositioner technology associated with this subtopic has been identified by E M Optomechanical, Inc. (EMOM) as a technology that could be incorporated into the company¿s long-working distance interference microscopes. A key element in these microscopes is a piezo-actuator device, installed in a manual pitch/yaw mount, which translates a small flat mirro ...

Magnetooptic Indicator (MOI) garnet films are an important non-destructive tool for imaging magnetic domains in a wide variety of applications from basic research to quality control. To be effectively used they must be 1) optimized for individual applications using interactive feedback from users, 2) standardized to allow comparison of data, 3) improved in quality and process control and 4) made g ...

Modern supercontinuum (SC) light sources are generated by non-linear interactions between ultrashort pulse lasers and optical fibers. Output in near-ultraviolet to near-infrared wavelength ranges has been demonstrated. These light sources have high brightness and are spatially coherent. Recently, output to 4.5 µm was achieved using fluoride glass fibers; optical absorption by the fiber prevents l ...

Modern supercontinuum (SC) light sources are generated by non-linear interactions between ultrashort laser pulses and optical fibers. These light sources have high brightness and are spatially coherent. Output in near-ultraviolet to near-infrared wavelength ranges has been demonstrated. SC wavelength ranges are constrained by the transmission and dispersion properties of the fibers. Previously, ou ...

MRC PROPOSES TO DEVELOP A SAFETY PERFORMANCE INDICATOR (PI) OF THE ELECTROMAGNETIC (EM) PROTECTION STATUS OF A NUCLEAR POWER PLANT (NPP). WE BELIEVE THAT SUCH A PI IS NEEDED BECAUSE: (1) EM ENVIRONMENTAL POLLUTION IS ON THE INCREASE,(2) ADDITIONAL EM THREATS MUST BE EVALUATED, AND (3) DISRUPTION OF NPP OPERATIONS BY EM EFFECTS CAN AND MUST BE AVOIDED. PREVIOUS STUDIES HAVE ADDRESSED THE ISSUE OF E ...
