摘要： A direct diode laser system includes N laser head assemblies (LHAs) generating N output beams, N optical fibers receiving respective N output beams and generating N received output beams, and a torch head recollimating and focusing the N received output beams onto a single spot. Preferably, each of the laser head assemblies of the direct diode laser system includes M modules generating M laser beams, wherein each of the M laser beams has a corresponding single wavelength of light. M-1 dichroic filters, wherein each of the M-1 dichroic filter transmits a corresponding one of the M laser beams and reflects all other wavelengths, and a fiber coupling device collecting the M laser beams to produce a respective one of the N output beams. In an exemplary case, the M-1 dichroic filters function as band pass filters. A method of generating a high fluence, high power laser beam is also described.

摘要： A fiber optic connector and an associated fabrication method where the connector has a connector housing having a base side, a and pair of sidewalls upstanding from the base side that are spaced apart in relation to each other, and each of the housing sidewalls define at least one aperture through which optical signals can be transmitted into and out of the housing by an input optical fiber and an output optical fiber, respectively, located in fixed positions outside the housing, a pair of optical lens elements are contained within the housing which collimate optical signals transmitted via the respective optical fibers, and a micro-alignable sensing fiber is arranged between the lens elements.

摘要： A method for measuring strain on a structure having a bore and an untethered fiber-optic strain gauge embedded in the bore, which includes the steps of inserting a coupler portion of a fiber-optic cable into the bore in operative relationship to the fiber-optic strain gauge, and using an optical cavity length measurement device attached to the distal end of the fiber-optic cable to measure the strain on the structure. The coupler portion of the fiber-optic cable is removed from the bore after the strain on the structure has been measured. In an illustrative embodiment, the structure is a fastener, e.g., a rivet, used to join together the aluminum skin and the airframe of an aircraft, the bore being provided coincident with the central, longitudinal axis of the rivet.

摘要： An optical fiber alignment assembly including an alignment fixture for controllably positioning an optical fiber including an optical fiber carrier defining at least one channel extending inwardly from a first surface of the optical fiber carrier which is adapted for receiving an optical fiber. The optical fiber carrier also defines at least one passageway from a second surface of the optical fiber carrier, opposite the first surface, to each channel. The passageway is at least partially filled with a thermal transfer material and an optical fiber bonding material is disposed within the channel and is adapted to bond an optical fiber to the optical fiber carrier. The optical fiber bonding material has a predetermined melting temperature such that by applying heat to the thermal transfer material, the optical fiber bonding material becomes at least partially malleable. Once the optical fibers are properly positioned in the malleable optical fiber bonding material, the thermal energy can be removed from the thermal transfer material such that the optical fiber bonding material resolidifies and fixes the position of the optical fiber. The optical fiber bonding material disposed in the channels adjacent to the heated channel can be cooled to prevent undesirable movement of the optical fibers in the adjacent channels.

摘要： A micro-aligner for precisely aligning an optical fiber with an optical device, and methods of making and using same. The micro-aligner includes a carrier having a surface plane and holds an optical fiber to be positioned in alignment with an optical device. Spring biased first and second microactuators are provided on the carrier for effecting in-plane movement and alignment of the optical fiber with an optical device in either or both of two orthogonal in-plane directions when either or both of said in-plane microactuators is activated. Backstops are located on the carrier in respective association with each of the first and second microactuators, respectively, such that the first and second backstops delimit the amount of return in-plane movement of the respective beam after either of the respective first or second microactuator is de-activated. A third microactuator also is provided on the carrier which, when activated, effectively deflects the carrier upward in a direction away from the base.

摘要： A fiber optic connector for establishing an optical connection with an optical fiber embedded within a composite structure is provided. The fiber optic connector includes a first lens element, such as a metal sheathed graded index (GRIN) lens, that is attached to the portion of the edge surface of the composite structure to which the optical fiber extends. The fiber optic connector also includes an alignment tube and a second optical fiber, external to the composite structure, having an end portion disposed within one end of the alignment tube. By sliding the other end of the alignment tube over the first lens element, optical communication is established between the first optical fiber embedded within the composite structure and the second optical fiber external to the composite structure. The fiber optic connector also typically includes a ferrule mounted upon the end portion of the second optical fiber and inserted at least partially into one end of the alignment tube. In order to effectively couple the optical signals between the embedded optical fiber and the external optical fiber, the fiber optic connector also generally includes a second lens element, such as a second GRIN lens, disposed within a medial portion of the alignment tube for collimating the optical signals.

摘要： A microactuator for precisely aligning an optical fiber with an optical device includes a carrier having at least one bimorphic actuator which bends or deflects in response to electrical stimuli to thereby controllably position the carrier and, in turn, an optical fiber mounted on the carrier, with an optical device, such as a laser diode. The bimorphic actuator includes first and second layers of first and second materials, respectively, which respond differently to electrical stimuli. For example, the first and second materials can have different coefficients of thermal expansion or one of the materials can be a piezoelectric material such that application of electrical stimuli to the bimorphic actuator will deflect the actuator by a precisely controllable amount. The carrier can also be mounted on an alignment support structure such that upon deflecting the bimorphic actuator is urged against a portion of the alignment support structure so as to move the carrier relative to the alignment support structure. Thus, by maintaining the alignment support structure in a fixed relation to the optical device, the carrier and, in turn, the optical fiber mounted on the carrier can be positioned in precise alignment with the optical device.
