Abstract: An optical probe for emitting and/or receiving light within a body comprises an optical fiber that transmits and/or receives an optical signal, a silicon optical bench including a fiber groove running longitudinally that holds an optical fiber termination of the optical fiber and a reflecting surface that optically couples an endface of the optical fiber termination to a lateral side of the optical bench. The fiber groove is fabricated using silicon anisotropic etching techniques. Some examples use a housing around the optical bench that is fabricated using LIGA or other electroforming technology. A method for forming lens structure is also described that comprises forming a refractive lens in a first layer of a composite wafer material, such as SOI (silicon on insulator) wafers and forming an optical port through a backside of the composite wafer material along an optical axis of the refractive lens.

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: 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 detector system comprises a hermetic optoelectronic package, an optical bench installed within the optoelectronic package, a balanced detector system installed on the optical bench. The balanced detector system includes at least two optical detectors that receive interference signals. An electronic amplifier system installed within the optoelectronic package amplifies an output of at least two optical detectors. Also disclosed is an integrated optical coherence tomography system. Embodiments are provided in which the amplifiers, typically transimpedance amplifiers, are closely integrated with the optical detectors that detect the interference signals from the interferometer. Further embodiments are provided in which the interferometer but also preferably its detectors are integrated together on a common optical bench. Systems that have little or no optical fiber can thus be implemented.

Abstract: 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.

Abstract: An optical power control system for a semiconductor source spectroscopy system controls power fluctuations in the tunable signal (210) from the spectroscopy system (100) and thus improves the noise performance off the system. This general solution has advantages relative to other systems that simply detect reference power levels during the scan and then correct the detected signal after interaction with the sample by reducing the requirements for coordinating the operation of the sample detectors and power or reference detectors. The spectroscopy system (100) comprises a semiconductor source (200, 610, 622) and a tunable filter (612). The combination of the semiconductor source (200, 610, 622) and tunable signal (210) illuminate a sample (10) with a tunable signal (210), being tunable over a scan band (510). The power control system comprises an amplitude detector system (320, 322) for detecting the power of the tunable optical signal (210) and power control system (410, 411, 318) for regulating the amplitude of the tunable optical signal (210) in response to its detected power.

Abstract: A spectrometer (100)that provides the ability to combine the advantages of high resolution, compactness, ruggedness, and low-power consumption of Fabry-Perot (FP) tunable filter spectrometer (105), with the multi-channel multiplexing advantage of FT and/or grating/detector array (118,130). The key concept is to design and operate a tunable FP filter in a multiple-order condition. This filter is then followed by a 'low-resolution' fixed grating, which disperses the filtered n-order signal into a preferably matched N-element detector array for parallel detection. The spectral resolution in this system is determined by the FP filter, which can be designed to have very high resolution. The N-order parallel detection scheme reduces the total integration or scan time by a factor of N to achieve the same signal to noise ratio (SNR) at the same resolution as the single channel tunable filter method.
