A method and apparatus for coupling light from an array of optoelectronic devices to a corresponding array of fibers contained in a fiber optic ferrule is disclosed. The fibers may be single-mode or multi-mode optical fibers. The method includes fixing the fiber optic ferrule to the optical subassembly (OSA) base upon which the array of optoelectronic devices will be affixed, aligning the array of optoelectronic devices to the corresponding array of fibers, then securing the array of optoelectronic devices to the OSA base. In one embodiment, the module includes an optical subassembly module housing a linear array of 1300 nm VCSELs or photodetectors, spaced apart at a 250 micron pitch to correspond to the spacing of optical fibers in a conventional MT ferrule. The array of optoelectronic devices is mounted on a substrate assembly that includes a weldable surface and one or more photodetectors for automatic power control. After the components are aligned, the substrate assembly is affixed to the OSA base by epoxying or welding.

In an exemplary embodiment of the present invention, an optical interface unit provides an interface between an optoelectronic device and industry standard MTP/MPO connectors. The optical interface unit axially aligns the core of a fiber with the optoelectronic device and interfaces that fiber to the standardized connector. In addition, the optical interface unit further provides a standardized interface for visible contact connection between the individual fiber stubs and the terminated fibers in the standardized connector. The optical interface unit therefore maximizes coupling from the optoelectronic device with the standardized connector.

A method and apparatus for driving lasers. An example laser driving system includes a laser current controller for providing a modulation signal and a bias signal. The modulation signal and bias signal is used by a plurality of high-speed current drivers that accept the modulation signal and the bias signal and produce a plurality of laser drive signals. The example system also has a disable input that disconnects power from a high-speed current driver when the high-speed current driver is not in use. The exemplary system develops the modulation and bias signals by feeding back a signal developed from detection of laser light from one of the lasers driven by the system. The laser may be a data laser or a control laser that is modulated by a signal having a lower frequency than the data lasers. If a control laser is used then the photodetector circuit used for feedback can have a lower frequency response because of the lower frequency of the control laser signal. The photodetector system may also employ a peak detector capacitor discharge circuit where a large capacitance is simulated by having the capacitor discharge through the base of a transistor have a current source in the emitter circuit.

An inventive transceiver includes a transmitter for outputting plural beams of electromagnetic energy. In the illustrative embodiment, the transmitter is a vertical cavity surface emitting laser. Plural beams output by the transmitter are directed to the detector by an array of diffractive optical elements. In the preferred embodiment, the optical elements are fabricated by imprinting a pattern on a high temperature film substrate using an ultraviolet epoxy. The use of a vertical cavity surface emitting laser allows for high data rates while the diffractive optical arrangement allows for a compact design.

An imaging method and associated system for producing high-resolution images. The method includes illuminating an object or scene with coherent radiation such as beams from a laser and then, collecting scattered light with a plurality of subapertures rather than a single large aperture. The method continues with coherently detecting, such as with heterodyne detection, the scattered light to measure the complex amplitude incident on each subaperture and digitally reconstructing images from the coherently detected light for the subapertures. Then digital co-phasing is performed on the subapertures using an image sharpness or quality metric to form an image having the resolution of the total subaperture area. The method may also include determining an aimpoint in the formed image, calculating a phase screen, directing laser beams through the subapertures towards the aimpoint, and co-phasing the laser beams by applying the phase screen to form a single beam.
