    摘要: Nano-silicates are the template for photonic control materials with research for a material allowing three-dimensional (3-d) photonic control ongoing for years. This author discovered a material that physically enables 3-d photonic control over the visible spectrum via the previously unidentified property of coherent poly propagation (CPP). CPP allows actualized 3-d photonic demultiplexing in several precious opal nano-silicate specimens. This is a working material that accurately demultiplexes, up/downconverts and propagates the shapes of several types of mono and polychromatic incident light sources. This material is a durable 3-d demultiplexing photonic waveguide that works without cables. The propagated shapes are able to be manually moved across the 3-d specimen surfaces. Other, previously unknown, properties displayed by this material: spectrophotometric and polariscopic play-of-color, plus photonic rotational symmetry. This material is environmentally friendly, in that it emits no beta or alpha particles, performs at ambient temperatures/pressures and is made of commonly available silica.

    摘要: A general purpose sensor architecture integrating a surface enhanced Raman spectroscopy (SERS) substrate, a diffractive laser beam delivery substrate and a diffractive infrared detection substrate is provided that can be used to implement a low-cost, compact lab-on-a-chip biosensor that can meet the needs of large-scale infectious disease testing. The sensor architecture can also be used in any other application in which molecules present in the liquid, gaseous or solid phases need to be characterized reliably, cost-effectively and with minimal intervention by highly skilled personnel.

    摘要: A 2D spatial differentiator operates in transmission and comprises a Si Nano rod photonic crystal that can transform an image, Ein, into its second-order derivative, Eout α∇2Ein, allowing for direct discrimination of the edges in the image. The use of a 2D photonic crystal allows for differentiation and edge detection in all directions with a numerical aperture (NA) up to 0.315 and an experimental resolution smaller than 4 μm. The nanophotonic differentiator is able to be directly integrated into an optical microscope and onto a camera sensor, demonstrating the ease with which it can be vertically integrated into existing imaging systems. Furthermore, integration with a metalens is demonstrated for realizing a compact and monolithic image-processing system. In all cases, the use of the nanophotonic differentiator allows for a significant reduction in size compared to traditional systems, opening new doors for optical analog image processing in applications involving computer vision.

    摘要: An apparatus for facilitating electromagnetic wave resonator tuning is disclosed, including first, second, and third spaced apart resonator portions, the second portion disposed between the first and third to form an electromagnetic wave resonator having a resonant frequency, wherein the first and second portions define a first volume therebetween and the second and third define a second volume therebetween, a first actuator coupled to the first portion, the second, or both, the first actuator configured to adjust a width of the first volume, and a second actuator coupled to the second portion, the third, or both, the second actuator configured to adjust a width of the second volume, wherein the actuators are configured to decrease the widths of the first and second volumes or increase the widths of the first and second volumes to adjust the resonant frequency of the resonator. Other apparatuses, methods, and systems are also disclosed.
