摘要： Generally, the present invention relates to a fiber optic device that is easier to align than conventional devices, and to a method for aligning such devices. An embodiment of the invention includes a first focusing element having an optical axis and a first focal length, and a first optical fiber optically coupled to a first side of the first focusing element. The first optical fiber is disposed at a first transverse distance from the optical axis so that light from the first optical fiber propagates on a second side of the first focusing element as a substantially collimated beam at a first angle to the optical axis. A wedged optical element is optically coupled to the second side of the first focusing element and deviates the substantially collimated beam so as to propagate in a direction substantially parallel to the optical axis.

摘要： A compact, in-line polarization combiner uses a folded, reflective optical path from a first fiber to a second fiber. The combiner includes first and second fibers at one end of an in-line package, and a third fiber at the other end of the in-line package. A first polarization-dependent optical path is defined between the first and second fibers for light in a first polarization state. A second polarization-dependent path is defined between the first and third fibers for light in a second polarization state orthogonal to the first polarization state. A polarizer is disposed between the ends of the combiner and reflects light on the first path between the first and second fibers and transmits light on the second path between the first and third ports, A reflector is disposed on the first path to reflect light to the polarizer.

摘要： The invention relates to an approach to angle tuning a thin film, interference filter device in which light is delivered to the filter from a fiber lying off-axis relative to the filter, and to a method of optically coupling such a device. The optical device comprises a lens unit having an optical axis and an adjustable effective focal length. The device also includes a first port disposed on a first side of the lens unit and on a first side of the optical axis, and an optical element disposed on the second side of the lens unit. The optical element has an optical characteristic that is dependent on the angle of incidence on the optical element. The lens unit has an adjustable focal length so light from the first port is incident on the optical element at a desired angle.

摘要： A system and method for directly measuring the alignment error in a fiber-optic coupler is disclosed. In one embodiment, an optical switch utilizes a beam deflection mirror. When the beam deflection mirror directs an incident light beam to a particular fiber, the incident light beam may enter the fiber at a location offset from the center of the fiber. When the incident beam is reflected at the opposite end of the fiber, the beam returns and exits the fiber exactly at the center of the fiber. The difference between the entry and exit points results in a return beam path different than the incident beam path. This different return beam path may be used to impinge upon a quadrant detector, whose anode currents may then contain a direct measurement of the distance between the entry and exit points on the fiber.

摘要： An apparatus for producing a tilt error signal representative of the tilt of an optical disk is disclosed. The apparatus includes a source of laser light for focusing a laser beam onto the disk and reflecting such beam from the disk, a beamsplitter positioned to receive the reflected light beam and to direct the light beam in a first direction, and a structure for separating the reflected light beam from the beamsplitter into at least four portions and for producing detection signals for each portion. The apparatus further includes circuitry responsive to the detection signals for producing first and second tracking error signals, the first and second tracking error signals being produced by different combinations of the detection signals and both being sensitive to cross-track diffraction, and circuitry responsive to the first and second tracking error signals for producing the tilt error signal.

摘要： In general, the mode field pattern of a single-mode polarization-maintaining fiber is symmetric. There are preferred axes for the polarization states, but the intensity pattern emerging from the fiber is rotationally symmetric. If a short piece of multi-mode fiber is spliced onto the end of a polarization-maintaining single-mode fiber, it is possible to change the apparent shape of the mode field. The use of a fusion splicer affects the stress pattern in polarization-preserving fiber, and introduces asymmetry into the shape of the fiber mode field. If the spliced fiber is cleaved near the splice, and the asymmetry of the fiber mode field is matched to the asymmetry of a laser diode beam, then the laser beam is coupled efficiently into the fiber without the use of additional beam-shaping optics. The asymmetric beam from the laser is brought to a focus, which is also asymmetric. By matching the asymmetries of the focused spot and the distorted mode field (caused by the addition of the short piece of multi-mode fiber), good coupling is achieved into the fiber. Once the light has entered the spliced fiber and propagated past the splice, the mode field returns to its original symmetric pattern and the light propagates in a single mode, as it would in an unspoiled, single-mode polarization-maintaining fiber. The output from the unspoiled end is still symmetric, and there is little attenuation caused by the splice.
摘要翻译：通常，单模维持光纤的模场模式是对称的。存在用于偏振态的优选轴，但是从光纤出射的强度图案是旋转对称的。如果短路多模光纤被拼接到偏振保持单模光纤的端部，则可以改变模场的表观形状。使用熔接器影响偏振保持光纤中的应力模式，并将不对称性引入光纤模式场的形状。如果拼接光纤在接头附近被切割，并且光纤模式场的不对称性与激光二极管光束的不对称性匹配，则激光束有效地耦合到光纤中，而不需要额外的光束整形光学器件。使来自激光器的不对称光束成为焦点，其也是不对称的。通过匹配聚焦点的不对称性和失真模场（由添加短模的多模光纤引起），纤维实现良好的耦合。一旦光已经进入拼接的光纤并传播通过接头，则模式场将返回其原始的对称图案，并且光以单模式传播，如同在未受污染的单模偏振保持光纤中。未破坏端的输出仍然是对称的，并且由接头引起的衰减很小。

摘要： An improved fiber optic tap monitor has characteristics that are flatter over the wavelength range of interest. The polarization dependence of the characteristics of the tap monitor is reduced, and the package for the tap monitor is smaller. The tap monitor reduces the amount of light reflected back to the source. The tap monitor is also assembled in a manner to improve temperature stability, so that its characteristics over a range of temperatures are more nearly constant.

摘要： Two sub-assemblies in a fiber optic device are fitted to respective end faces of a central section, along a longitudinal axis. The end faces of the central section are non-parallel. Butting the sub-assemblies to respective ends of the central section permits relative adjustment of the two sub-assemblies in substantially decoupled degrees of freedom. This results in a simpler adjustment procedure for aligning the two sub-assemblies. Furthermore, the mounting of the sub-assemblies using angled faces permits the use of relatively thin layers of adhesive that reduce misalignment problems arising from mismatched thermal expansion when the temperature changes.
