Abstract:
Materials and Methods related to diagnosing a clinical condition in a subject, or determining the subject's predisposition to develop the clinical condition, using a multi-parameter system to measure a plurality of parameters and an algorithm to determine a disease score.
Abstract:
Fiber optical devices formed on substrates fabricated with grooves that operate based on evanescent optical coupling through a side-polished fiber surface in each fiber involved.
Abstract:
Fiber optical devices formed on substrates fabricated with grooves that operate based on evanescent optical coupling through a side-polished fiber surface in each fiber involved. An index-changing liquid is used to control the evanescent optical coupling in response to a control signal.
Abstract:
Thin-film techniques in forming fiber devices that engage fibers to a substrate with different material properties. Structure buffering, diffusion bonding, and thickness monitoring may be achieved by such thin-film techniques.
Abstract:
Optical wavelength-division multiplexers and demultiplexers based on Mach-Zehnder interferometers via evanescent coupling through a side-polished fiber port of a fiber.
Abstract:
Techniques for forming fiber devices that engage fibers to a substrate with similar material properties. A semiconductor template may be used to define positions and orientations of the fibers.
Abstract:
Techniques and devices for integrating optical fibers on substrates with grooves for various optical applications. Two openings that penetrate through the substrate are formed at both ends of each groove to allow a fiber to pass from one side of substrate to another side. The fiber cladding of a fiber portion positioned in the groove can be removed to produce an optical coupling port.
Abstract:
A radiation detector for detecting ionizing radiation. The detector includes a semiconductor having at least two sides. A bias electrode is formed on one side of the semiconductor. A signal electrode is formed on a side of the semiconductor and is used to detect the energy level of the ionizing radiation. A third electrode (the control electrode) is also formed on the semiconductor. The control electrode shares charges induced by the ionizing radiation with the signal electrode, until the charge clouds are close to the signal electrode. The control electrode also alters the electric field within the semiconductor, such that the field guides the charge clouds toward the signal electrode when the clouds closely approach the signal electrode. As a result, trapping of charge carrying radiation (i.e., electrons or holes) is minimized, and low-energy tailing is virtually eliminated.
