摘要： An improved system and method for automated fiber polishing overcomes the limitations of conventional systems and methods. In particular, the present invention provides for continuous determination of the quality of the polish during a polishing procedure. An optical signal is transmitted to a fiber tip, and any back-reflected signal is detected and monitored to determine polish quality. In this manner, automated polishing quality assurance is provided in real time.

摘要： An optical component is adapted for pick-and-place-style installation on an optical submount or bench and compatible with a chuck of a bonder that picks-up the optical component, places it on the optical bench, and then typically solder bonds the optical component to the bench. In the current implementation, this optical component comprises an optical element, such as an optical fiber, lens, or MOEMS device, that is attached to a plastically deformable mounting structure. The optical component has a bench-attach surface that is used to bond the optical component to an optical bench. Further, the optical component has a bonder chuck engagement surface to which a bonder chuck attaches to manipulate the optical component, such as install it, on the optical bench.

摘要： A semiconductor optical amplifier system comprises a hermetic package. In the typical implementation, this hermetic package is a standard 0.75 inch×0.5 inch package, such as a butterfly package. An optical bench is sealed within this package. A first fiber pigtail enters this package via a feed-through to connect to the bench and terminate above the bench. A second optical fiber pigtail enters the package via a second fiber feed-through to connect to the bench and similarly, terminate above the bench. A semiconductor amplifier chip is connected to the bench to provide amplification. Isolators are further incorporated along with a monitoring diode to yield a fully integrated system.

摘要： Integrated spectroscopy systems are disclosed. In some examples, integrated tunable detectors, using one or multiple Fabry-Perot tunable filters, are provided. Other examples use integrated tunable sources. The tunable source combines one or multiple diodes, such as superluminescent light emitting diodes (SLED), and a Fabry Perot tunable filter or etalon. The advantages associated with the use of the tunable etalon are that it can be small, relatively low power consumption device. For example, newer microelectrical mechanical system (MEMS) implementations of these devices make them the size of a chip. This increases their robustness and also their performance. In some examples, an isolator, amplifier, and/or reference system is further provided integrated.

摘要： An optical membrane device comprises a substrate, at least one support block on a surface of the substrate, and at least one plate. A torsion beam supports the plate above the substrate on the support block. The optical membrane device also includes an optical membrane structure supported by the plate above the substrate and at least one electrode on the substrate underneath the plate. In one implementation, the optical membrane device further comprises a tether for coupling the optical membrane structure to the plate. The tether extends between the optical membrane structure and the plate. In another implementation, the substrate of the optical membrane device has an optical port through the substrate directly below the optical membrane structure. The plate is substantially balanced around the torsion beam to minimize a sensitivity to orientation in a gravitational field.

摘要： A frequency swept laser source for TEFD-OCT imaging includes an integrated clock subsystem on the optical bench with the laser source. The clock subsystem generates frequency clock signals as the optical signal is tuned over the scan band. Preferably the laser source further includes a cavity extender in its optical cavity between a tunable filter and gain medium to increase an optical distance between the tunable filter and the gain medium in order to control the location of laser intensity pattern noise. The laser also includes a fiber stub that allows for control over the cavity length while also controlling birefringence in the cavity.

摘要： A near infrared (NIR) semiconductor laser system is shown for gas sensing. An embodiment is centered on the use of a system with a much wider tunable laser, which today has a scan band of more than 150 nanometers (nm) to as much as 250 nm or more. In some cases the scan band is about 400 nm or more. This is achieved in the current embodiment through the use of a widely tunable microelectromechanical system (MEMS) based Fabry-Perot filter as an integral part of the laser cavity. Using this technology, these systems are capable of capturing a variety of gases in the any of the well-known spectroscopic scan bands, such as the OH, NH or CH. For example, a single laser with a 250 nm scan band window between 1550-1800 nm can capture ten or as many as twenty hydrocarbon-based gases simultaneously.

摘要： A tunable laser spectroscopic carpet identification system comprises a tunable laser spectroscopy system for generating a tunable signal that is transmitted to a carpet sample. The system detects the tunable signal after interaction with the carpet sample so that an analyzer is able to relate a spectral response of the carpet sample to a chemical composition of the carpet sample. In one example, the spectroscopy system comprises a laser cavity in which the tunable signal is generated, a semiconductor gain medium in the laser cavity, and a tunable element for controlling a wavelength of tunable signal generated in the laser cavity. To deal with variations in water content, the analyzer estimates a water content of the carpet sample using the spectral response of the carpet sample and then determines the chemical composition of the carpet sample in part based on the estimate of the water content.

摘要： A detector system for a fiber optic component is insensitive to stray light. Specifically, the invention comprises a detector chip, which converts received light into an electric signal. A baffle substrate is positioned over the detector chip. This baffle substrate has a transmission port through which an optical signal is transmitted to the detector chip. As a result, light that is not directed to be transmitted through the port is blocked by the baffle substrate. In this way, it rejects stray light that may be present in the hermetic package. A detector substrate is provided on which the detector chip is mounted. This detector substrate preferably comprises electrical traces to which the detector chip is electrically connected. The detector substrate can further comprise bond pads for wire bonding to make electrical connections to the electrical traces.
