摘要： A pattern method is provided for testing an optical lens. The method provides a lens for test, including a first lens surface with a focal plane in object space and a second lens surface with a focal plane in image space. Also provided is a pattern test fixture including an imaging device and a target pattern. The lens is positioned so that the imaging device is located outside the object space focal plane and the target pattern located is outside the image space focal plane. The imaging device, such as a microscope, magnification device, human eye, or camera, is used to view the target pattern. A viewed image representation of the target pattern is received in the imaging device and compared to the target pattern. More typically, the viewed image representation is compared to a target pattern copy.

摘要： A Free Space Optics (FSO) connector is provided with a method for interfacing to an electronic circuit card electrical connector via the FSO connector. The method transceives electrical signals via an electronic circuit card electrical connector. Using an FSO connector, the method converts between electrical signals and optical signals, and transceives optical signals via free space. In one aspect, the optical signals are initially received via free space along a first axis, and reflected along a second axis. Further, the optical signals may be initially transmitted along the second axis and reflected into free space along the first axis. In another aspect, the optical signals are transceived in a plurality of directions in free space. For example, optical signals may be transmitted and received in four mutually-orthogonal axes.

摘要： A method is provided for performing chromatic dispersion (CD) compensation. A zero-forcing filter is calculated with a number of taps (n) required to nullify a chromatic dispersion frequency response of an optical channel. The number of taps in the zero-forcing filter is truncated to a number equal to (n−x), where x is an integer greater than 0. In one aspect, the chromatic dispersion frequency response of the optical channel is partitioned into a plurality of constituent chromatic dispersion responses, and a zero-forcing filter is calculated for each of the plurality of constituent chromatic dispersion responses. The number of taps in each of the plurality of zero-forcing filters is truncated, and the CD compensation filter is formed for each of the plurality of truncated tap zero-forcing filters. In another aspect, the tap values of the zero-forcing filter are quantized to a finite quantization set.

摘要： A method and system are provided for aligning the optic port of a device having a Free Space Optics (FSO) connector. In a link device with an FSO connector, a controller determines that an optic port alignment procedure is required. A lens is set to an initial wide beam dispersion mode, and a mirror is set to an initial position angle. Note: the lens and mirror may be the FSO connector receive path or transmit path. An optical signal is communicated at a first low baud rate, and the first baud rate communications are optimized by iteratively adjusting the mirror and narrowing the lens focus. Then, an optical signal is communicated at a second baud rate, faster than the first baud rate, and the second baud rate communications are optimized by iteratively adjusting the mirror and narrowing the lens focus.

摘要： A photodetector with a bandwidth-tuned cell structure is provided. The photodetector is fabricated from a semiconductor substrate that is heavily doped with a first dopant. A plurality of adjoining cavities is formed in the semiconductor substrate having shared cell walls. A semiconductor well is formed in each cavity, moderately doped with a second dopant opposite in polarity to the first dopant. A layer of oxide is grown overlying the semiconductor wells and an annealing process is performed. Then, metal pillars are formed that extend into each semiconductor well having a central axis aligned with an optical path. A first electrode is connected to the metal pillar of each cell, and a second electrode connected to the semiconductor substrate. The capacitance between the first and second electrodes decreases in response to forming an increased number of semiconductor wells with a reduced diameter, and forming metal pillars with a reduced diameter.
