Abstract: In a free space communication network in which different communication nodes are linked together by directed beams, a method for dynamically configuring the topology of the network allows the transmission directions of the communication nodes to be autonomously changed to communicate with a new node as dictated by the needs of the network. Moreover, the nodes can be switched from directional to broadcast and back again on an as-needed basis. The network consists of a topology that can be rapidly and physically reconfigured as required to provide multiple connectivity, a desired quality of service, or to compensate with the loss of communication links between nodes. The loss of direct communication between any two nodes in an optical network can occur because of obscuration of the atmospheric path between the two nodes. The directed beam which provides the communication channel between the two nodes can, in this situation, be steered to direct its energy towards another accessible node.

Abstract: A method of forming a fiber probe having an aperture for use in near-field scanning optical microscopy. The method includes a first steps of coating an optical fiber having a tapered tip with a metal layer. Next is a step of milling the tapered tip and metal layer such that an aperture is formed through the metal layer at the tapered tip. The milling step includes focused ion-beam milling the tapered tip and metal layer. The focused ion-beam milling can be done by raster scanning the focused ion-beam in a rectangular pattern at an apex of the tapered tip. Also, the fiber probe made through the above outlined method is used in near-field scanning optical microscopy.

Abstract: An optical fiber is tapered, preferably adiabatically, and has a material coated on it for chemical bonding with fluorophores. When the fluorophores couple with the material, evanescent radiation generated fibers causes the fluorophores to fluoresce, and the fluorescence is coupled back into the fiber.

Abstract: A far-field optical microscope capable of reaching nanometer-scale resolution using the in-plane image magnification by surface plasmon polaritons is presented. The microscope utilizes a microscopy technique based on the optical properties of a metal-dielectric interface that may, in principle, provide extremely large values of the effective refractive index neff up to 102-103 as seen by the surface plasmons. Thus, the theoretical diffraction limit on resolution becomes λ/2neff, and falls into the nanometer-scale range. The experimental realization of the microscope has demonstrated the optical resolution better than 50 nm for 502 nm illumination wavelength.

The thermal emitter includes a vertically aligned carbon nanotube (VACN) array. The VACN array includes a plurality of carbon nanotubes disposed proximate to a thermally conductive substrate, such that a longitudinal axis of the carbon nanotubes extends substantially perpendicular to a surface of the substrate. The thermal emitter absorbs the visible light from the light emitter and converts the visible light from the light emitter into IR radiation.

Abstract: In a sensor system, an active sensor chip includes an array of periodically-patterned dielectric active sensor patches of different periodicities and geometries formed on a metal film. A specimen under study is positioned on each patch, and the active sensor chip is interrogated by illumination the patches in a predetermined sequence to result in a fluorescence response from each patch enhanced by SPP. The intensity of the fluorescence response is controlled by varying the wavelength, incidence angle, azimuthal orientation and polarization direction of the excitation light beam as the function of the periodicity of the illuminated patch. The system is compatible with commercial fluorescence microscopes and scanned laser interrogation systems.

Abstract: A system (10) for optical processing based on light-controlled photon tunneling is provided. The system (10) includes a prism (12) having a metallic film layer (14) formed on an upper surface thereof. The metallic film layer (14) has a microscopic aperture (18) formed therethrough and the microscopic aperture (18) is covered by a layer of non-linear optical film. A first light beam (30) is projected towards aperture (18) and photons from first light beam (30) tunnel through aperture (18). A second light beam (32) is also projected towards microscopic aperture (18), with the second light beam (32) having a different wavelength than that of light beam (30). Selective actuation and modulation of light beam (32) allows for selective control over the rate and intensity of the photons which tunnel through microscopic aperture (18). The intensity of transmission of the photons from light beam (30) are measured by optical fiber tip (22), thus allowing for the creation of optical gates, switches, and other optical processing devices.
