摘要： The present invention provides a substrate that overcomes the performance limitations of conventional microscope slides, microarrays, or microtiter plates when optically interrogated through the thickness of the substrate. With conventional microscope slides, image quality and resolution are degraded as a result of distortions introduced by imaging through the thickness of the glass. Fiber Optic Interrogated Microslides (FOI) consist of many fiber optics that have been fused together. When sliced and polished to form microscope slides, the fibers effectively transfer optical images from one surface of the microslide to the other. The finished microslide is the optical equivalent of a zero thickness window. The image of an object on the top surface is transferred to the bottom surface allowing it to be viewed without focusing through the thickness of the slide. In addition to providing improved image quality, FOI microslides allow objects to be directly imaged without complex and expensive focusing optics.

摘要： The invention features a fiber optic coupler package including a rigid substrate and at least two side-by-side optical fibers joined in a coupler region. The substrate has a coefficient of thermal expansion substantially matched to that of the fibers. Each fiber extends axially to opposite sides of the coupler region to a primary and secondary regions of fixation, at each side of the coupler region. In the primary region of fixation, each fiber is separately bonded in close proximity to a rigid mounting surface of the substrate using a small amount of adhesive contiguously disposed on opposite sides of the line of tangency formed by the fiber and the mounting surface. The adhesive is distributed to form a pair of substantially identical masses with mirror symmetry relative to a plane defined by the central fiber axis and the line of tangency. In the secondary region of fixation, extended outward from the coupling region beyond the primary regions of fixation, each fiber has a buffer coating and the fiber is bonded through the buffer coating to the substrate. The coupling region may be formed by the biconically tapered laterally fused process or by bonding the fibers together. The fibers of the coupler may be PM fibers, single mode fibers, multimode fibers, or their combination.

摘要： Fiber optic power splitters having a central fiber and a selected number of surrounding fibers spaced periodically around the central fiber and the method of fabricating such splitters are described. For splitters having between three and five surrounding fibers, the central fiber is made to have a reduced diameter relative to the surrounding fibers so that it contacts each of the surrounding fibers and each of the surrounding fibers, likewise, touches each of its neighboring fibers. For splitters having seven or more surrounding fibers, the diameters of the surrounding fibers are reduced relative to the central fiber so that mutual contact is made among the set of equal diameter surrounding fibers and the central fiber. The equation governing the relative diameters of the central and surrounding fibers, and methods of obtaining uniform diameter reduction in an optical fiber are described. Single-mode splitters made according to these means have relatively low variation of splitting fraction with variations of input optical power wavelength and can be made to distribute optical power input in any fiber among, e.g. three to seventeen outputs according to predeterminable relationships. Of particular practical importance, splitters can be made which split one input into four, eight, twelve, or sixteen equal outputs, having a flattened response over a significant wavelength range.

摘要： The invention is a fiberoptic coupler formed by multiple optical fibers each having a core and a surrounding cladding and at least one spacer fiber having the refraction index substantially matched to the refraction index of the cladding of at least one adjacent optical fiber. The optical and spacer fibers are arranged, over a region extending axially through a limited length coupling region, in a side-by-side configuration wherein each fiber touches neighboring fibers. The coupling region is created by laterally fusing all fibers and is adapted to couple propagating modes of light between the optical fibers. Various configurations of the coupler include an arrangement of seven equal diameter fibers with a center fiber surrounded by six fibers, or an arrangement of nineteen equal diameter fibers with a center fiber surrounded by a first ring of six close-packed fibers and a second ring of twelve close-packed fibers. The number of the optical fibers and spacer fibers and their relative arrangements are selected to achieve desired properties of the coupler such as a number of optical input and output fibers, the coupling ratio or wavelength dependent coupling.

摘要： A routing device for changing the direction of a fiberoptic path from a first axis to a second axis comprising a length of optical fiber having first and second directed fiber portions aligned with the first and second axes, respectively, and having a mid-potion extending through an arc of radius of the order of 2 cm or less; the mid-portion of the fiber having been treated to have a substantially reduced diameter relative to the directed fiber portions. In certain preferred embodiments, the diameter of the mid-portion of the fiber is sufficiently reduced to achieve an air-cladded state. Preferably the routing device includes an outer member for fixing the first and second directed portions relative to one another. The mid-fiber portion is preferably reduced by etching, polishing, or drawing (e.g., differential speed unidirectional drawing). Bent sections of the fiber are thermally annealed forming stress-free bends of minimum bend radius for long term applications. The fiber may also be twisted about its longitudinal axis. Bend or twist tolerant regions and annealed bends are preferably packaged separately or built integrally into a wide range of fiberoptic components, sensors, networks, or systems, with significant space savings, added performance features and mechanical flexibility.

摘要： An optical interferometer matrix is described which includes a reference waveguide for optically transmitting a reference signal. The optical interferometer matrix further includes a signal source waveguide for optically transmitting a source signal which has been modulated with respect to the reference signal in response to an applied physical effect. The physical effect may be, for example, thermal, acoustic, hydrodynamic, electrical, electromechanical or magnetic. The reference and signal waveguides are then optically coupled to one another at two different points so that interference between the light in the waveguides occurs under two different phase conditions, with a phase difference between these conditions which approaches .pi./2 radians. In the preferred embodiment, the two points of optical coupling are confined in a small space so that thermal- or pressure-induced differential phase changes of light between the first and second coupling points are negligible.

摘要： An interferometer is disclosed for optically sensing displacements in a surface. A first fiber optic waveguide receives light from a laser in one end and transports it to the other end where a portion is back reflected and a portion is projected upon the surface. The reflected light from the surface re-enters the fiber optic at the projecting end and combines with the back reflected signal to derive an optical information wave. This optical information wave is evanescently coupled to a second fiber optic waveguide which transports this wave to a detector. A specific amount of reflective matter is attached to the end of the first fiber optic waveguide to enhance reflection therefrom, and an optical energy absorber is fixedly attached to the other end of the second fiber optic waveguide to prevent internal back reflection within the second fiber optic waveguide.

摘要： An optical transducer (10) having a plurality of concentric cores (15,17). An intermediate cladding (16) is disposed between the inner and outer cores and an outer cladding (18) surrounds the outer core to define a symmetrical cylindrical transducer structure. Light propagated through the inner core (15) from a source (19) is coupled into the outer core (17) as a result of penetration of the evanescent electric field from the light in the inner core through the inner cladding (16) to the outer core. Control of the coupling length may be effected by suitable selection of the transducer structure parameters. At least one of the portions of the transducer is formed of an acousto-optically variable material whereby an acoustic field acting on the transducer causes a modulation of the coupled light so as to provide in the outer core (17) a modulated light signal suitable for detection by a receiver (21). Localized control of the parameters of the transducer may be effected to provide focusing of the coupled light. An electrical signal may be provided for controlling the coupling between the core portions.
