    Abstract: Optical switches and logic devices comprising microstructure-doped nanocavity lasers are described. These switches and logic devices have gain and thus can be cascaded and integrated in a network or system such as for example on a chip. Exemplary switching elements switch the intensity, wavelength, or direction of the output. Exemplary logic devices include AND, OR, NAND, NOR, NOT, and XOR gates as well as flip-flops. Microfluidic sorting and delivery as well as optical tweezing and trapping may be employ to select and position a light emitter in an nanooptical cavity to form the nanolaser.

    Abstract: Systems and methods for manipulating light with tunable ferroelectric photonic devices. Devices having tunable properties that exhibit photonic bandgap behavior are fabricated from ferroelectric materials. Apparatus is provided to apply tuning signals to the ferroelectric material using one or more of electric fields, mechanical forces, optical fields, and thermal fields. Control circuitry is provided to generate the control signals needed to apply the tuning signals. Input and output ports are provided to allow input signals to be received and to provide output signals. In some cases, a feedback loop is provided to use a portion of the output signal as a diagnostic signal for control of the operation of the device within an acceptable range. It is expected that ferroelectric photonic devices operating according to principles of the invention will be useful for a wide variety of applications, including optical switching, optical modulation, optical computing, and performing logic optically.

    Abstract: Systems and methods for obtaining two- and three-dimensional magnetic resonance images by using azimuthally symmetric dipolar magnetic fields from magnetic spheres. A complete two- or three-dimensional structured rendering of a sample can be obtained without the motion of the sample relative to the sphere. Magnetic spheres in the range of 100 μm and 100 nm are used with samples that are approximately one-tenth as large as the magnetic sphere. Sequential positioning of the integrated sample-sphere system in an external magnetic field at various angular orientations provides all the required imaging slices for successful computerized tomographic image reconstruction. The requirement to scan the sample relative to the magnetic tip is eliminated. Resolutions approaching atomic dimensions are expected to be obtained.

    Abstract: The development of a high-throughput multi-antigen microfluidic fluorescence immunoassay system is illustrated in a 100-chamber PDMS (polydimethylsiloxane) chip which performs up to 5 tests for each of 10 samples. Specificity of detection is demonstrated and calibration curves produced for C-Reactive Protein (CRP), Prostate Specific Antigen (PSA), ferritin, and Vascular Endothelial Growth Factor (VEGF). The measurements show sensitivity at and below levels that are significant in current clinical laboratory practice (with SIN>8 at as low as 10 pM antigen concentration). The chip uses 100 nL per sample for all four tests and provides an improved instrument for use in scientific research and “point-of-care” testing in medicine.

    Abstract: The invention is directed to different methods for controlling the positions of the guided modes of the photonic crystal waveguides. Methods based on both rearrangement of the holes and changing the size of the holes are presented. We have observed and explained the appearance of acceptor-type modes and the donor-type waveguides. The ability to tune frequencies of the guided modes within a frequency bandgap is necessary in order to achieve efficient guiding of light within a waveguide (reduced lateral and vertical waveguide losses) as well as to match frequencies of eigen modes of different photonic crystal based devices in order to have good coupling between them.
