Abstract: A multi-stripe laser diode chip (120) is integrated with a beam combiner (102) on a single optical bench (100), and is thus, applicable to placement in a single pigtailed module. Specifically, multiple beams (150A, 150B) emitted from the chip stripes (110A, 110B) are spatially merged using a birefringent material (500) and then coupled into an optical fiber (700). The use of the birefringent material provides an efficient solution for generating the merged beam (520), which can be coupled into a single optical fiber.

Abstract: An optical component 100 adapted for attachment to an optical bench or submount has an alignment feature 310 that is used in the positioning of the optical component 100 relative to the optical bench. This alignment feature 310 is formed in an exterior wall 210 of the optical component. Further, according to the preferred embodiment, the alignment feature 310 has a re-entrant sidewall 320. This last characteristic facilitates the identification of precise location of the alignment by a vision system, for example, thus, allowing the accurate placement and installation of the optical component on the optical bench 10.

Abstract: 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.

Abstract: An optical coherence tomography system utilizes an optical swept source that frequency scans at least two different sweep rates. In this way, the system can perform large depth scans of the sample and then the same system can perform shorter depth high precision scans, in one specific example. In order to optimally use the analog to digital converter that samples the interference signal, the system further samples the interference signals at different optical frequency sampling intervals depending upon the selected sweep rates of the optical swept source. This allows the system to adapt to different sweep rates in an optimal fashion.

Abstract: A sensor wire system with an integrated power source and wireless transmission is provided. A sensor wire includes a distal end that is inserted into a blood vessel of a patient's body. A sensor that is mounted at the distal end of the sensor wire and an electronics unit of the distal end of the sensor wire transmit information generated by the sensor to a receiver unit outside of the patient's body wirelessly. The system further includes a power source, which in one example is mounted to the distal end of the sensor wire, that supplies power to the electronics unit. Preferably the wire body functions as an antenna for the wireless broadcasting.

Abstract: An optical coherence analysis system uses a laser swept source that is constrained to operate in a mode locked condition. This is accomplished by synchronously changing the laser cavity's gain and/or phase based on the round trip travel time of light in the cavity. This improves high speed tuning by taking advantage of frequency shifting mechanisms within the cavity and avoids chaotic laser behavior.

Abstract: A multi semiconductor source tunable spectroscopy system has two or more semiconductor sources for generating tunable optical signals that are tunable over different spectral bands. The system enables the combination of these tunable signals to form an output signal that is tunable over a combined band including these individual spectral bands of the separate semiconductor sources. The system further compensates for spectral roll-off associated with the semiconductor sources. Specifically, near the limits of the semiconductor sources spectral bands, the power in the tunable signal tends to degrade or decrease. The system compensates for this roll-off using drive current control, attenuators, or electronic compensation.

Abstract: An alignment structure (100) maintains an optical fiber in a bore (113). The structure is fixed on a bench and is passively or actively aligned with a light source. Then the structure may be welded or soldered to the optical bench whereby the alignment may suffer due to heat transfer. To correct this, the alignment structure can be plastically deformed to correct the alignment after the components have been fixed. The alignment structure has a substantially constant cross section in a z-axis direction as well as flexible links in order to allow displacements orthogonal to the optical axis. This movement will be initiated by seizing the component with a micro-positioner at a handle (136) and displacing it over the elastic limit to achieve permanent deformation.
