Abstract: Systems, methods, devices, and computer program products are directed to mobility control and performance prediction in directional wireless networks. Network coverage and connectivity are optimized. Convex and non-convex network modeling is implemented to provide adaptive topology control and mobility control within the network, whereby communication links are retained, released, or reconfigured based on their communication role within the network architecture. Optionally or alternatively, network health is monitored, future network failure or degradation conditions are predicted, and the network reconfigures responsive to the predictions to avoid the failure or degradation conditions.

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.

Abstract: A system and method for optical wireless communication with fading resistance. A delayed diversity approach reduces fading significantly. Data is sent in a set of light signals (also called diverse light signals) which each have a different polarization and/or a different wavelength. The diverse light signals are also temporally different in that they are transmitted in a delayed fashion with respect to one another. In this way, each light signal is carried over a different, uncorrelated “channel” through the atmosphere. At a receiver, original data in each received light signals is temporally adjusted and combined into a single output data signal. The accuracy of each bit in the output data signal is then due to the reception of the combined diverse light signals. In this way, even if fading occurs in one channel (effecting one diverse light signal), a combined output data signal can still be generated at relatively high accuracy from the original data carried in one or more of the other diverse light signals.

Abstract: A magnetometer uses a material exhibiting the Faraday effect, in which the polarization of light transmitted through the material is changed in response to a magnetic field. When the material is placed in a Fabry-Perot cavity, multiple reflections of the light within the Fabry-Perot cavity increase the change in polarization and thus the sensitivity of the magnetometer. Other effects that alter the polarization of light can be employed instead.

Abstract: The invention uses a heterodyne interferometer with coherent detection that uses a vibrating sample that can be used as a non-contact and non-destructive surface profiler and mapping apparatus where detailed profiles of the local slope and/or roughness of the vibrating sample are obtained in three dimensions. The invention can operate in either a heterodyne or homodyne regime with a probe that uses either i) focused optics, ii) a single mode optical fiber with an integral GRIN lens at its far end for focusing onto the sample or iii) a single-mode optical fiber with a taper at the end. Additionally, the heterodyne interferometry technique can be used for imaging birefringent objects such as semiconductor diagnostics of GaAs, InGaAs, InGaAsP, and other II-VI of III-V binary, ternary, and quaternary materials for analysis and diagnostics by using the birefringent properties of the object, and monitoring the electrical activity of biological cellular tissue.

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.
