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： 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： 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.

摘要： Two sub-assemblies in a fiber optic device are fitted to mounting faces of a central section. The mounting faces are typically flat and mutually orthogonal, thus permitting the adjustment of the two sub-assemblies in 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 the orthogonal mounting faces permits the use of relatively thin layers of adhesive that reduce misalignment problems arising from mismatched thermal expansion when the temperature changes.

摘要： A particular focusing arrangement in a dual fiber collimator improves the transmission efficiency and ease of alignment of the collimator. In particular, the collimator includes two optical fibers mounted in a dual-fiber ferrule. The fiber end-faces are co-planar with the angle-polished end-face of the ferrule and displaced along the optical axis of the ferrule. The collimator unit also includes a first focusing element centered along the optical axis of the ferrule and positioned such that its back front focal point is between the two end faces of the fibers. An advantage provided by this arrangement is that by changing the fiber polish angle and polish azimuth, relative to a line connecting the fiber centers, superior coupling from one fiber to the other can be achieved, even with different working distances and at various wavelengths.

摘要： A coarse position sensor is provided for an optical recording device to generate a substantially linear coarse position signal, indicative of the position of a coarse carriage along the range of its travel, and which also is substantially immune to environmental and device variations. The sensor includes a light source mounted to a drive frame at one end of the range of travel, a position sensitive device fixed to the frame at the opposite end of the range of travel and facing the light source, and a deflecting optical element mounted to the coarse carriage in the path of the light. As the coarse carriage travels along its stroke between the inner and outer diameters of the optical disk, the amount of deflection of the light beam on the position sensitive device from a reference location will change. Based upon a trigonometric equation, a coarse position signal generator receives the output of the position sensitive device and generates a substantially linear coarse position signal indicative of the position of the coarse carriage.

摘要： This invention provides an equal path length lateral shearing interferometer and its implementation in focus detection devices, particularly for optical data storage devices. The interferometer comprises a beamsplitter and two abutting roof prisms. Shifting the placement of a roof prism along an axis orthogonal to the direction of light propagation and to the peak of the roof creates a lateral shear between the two output beams. Rotation a roof prism about this axis produces a tilt between the two output beams. This creates an interference pattern with a rotational orientation which is a function of the focus of the beam impinging on the optical storage medium. A pattern sensor is provided to adjust the focus of the beam in an accurate and dynamic manner.
