A new class of surface plasmon waveguides is presented. The basis of these structures is the presence of surface plasmon modes, supported on the interfaces between the dielectric regions and the flat unpatterned surface of a bulk metallic substrate. The waveguides discussed here are promising to have significant applications in the field of nanophotonics by being able to simultaneously shrink length, time and energy scales, allowing for easy coupling over their entire bandwidth of operation, and exhibiting minimal absorption losses limited only by the intrinsic loss of the metallic substrate. These principles can be used for many frequency regimes (from GHz and lower, all the way to optical).

Methods for integrated electronic and photonic design include laying out electronic and photonic design components in a design environment; adjusting photonic components according to photonic design requirements using a processor; checking design rules for electronic and photonic components according to manufacturing requirements; and adjusting component positioning and size to reconcile conflicts between electronic and photonic components.

A device for generation of genuine random numbers, uses quantum stochastic processes in optical parametric nonlinear media. The dimensionality of the random numbers is varied from 2 to over 100,000. Their statistical properties, including the correlation function amongst random numbers, are tailored using linear and nonlinear optical circuits following the parametric nonlinear media. Both the generation and manipulation of random numbers are integrated on a single nanophotonics chip. By incorporating optoelectric effects, fast streams of random numbers are created in custom statistical properties, which are updated or reconfigured in real time, such as at 10 GHz speed. The unpredictability of the random numbers is quantifying by evaluating their min-entropy. The genuineness of quantum random numbers is tested using both statistical tools and independently verified by measuring the quantum entanglement between the photons in real time.

The invention discloses a preparing method and application of an orthorhombic phase cesium-lead iodide monocrystal nanowire. The preparing method comprises the steps of adding lead iodide to gamma-butyrolactone which is in a protective atmosphere and under stirring at the temperature of 68.5-72.5 DEG C, so that brick red turbid solution is obtained; then adding cesium iodide to the brick red turbid solution to obtain mixed solution; placing the mixed solution in a protective atmosphere at the temperature of 68.5-72.5 DEG C to be stirred constantly for at least 80 min to obtain luminous yellow mixed solution; cooling the luminous yellow mixed solution, and placing the luminous yellow mixed solution in an environment with relative humidity smaller than or equal to 20% and temperature of 68.5-72.5 DEG C to be evaporated to dryness, so that the orthorhombic phase cesium-lead iodide monocrystal nanowire is obtained, wherein the single crystal growth direction of the nanowire is <100>, wire diameter is 0.1-0.15 micron, and wire length is larger than or equal to 100 microns. The nanowire can serve as a basic unit to build a nanowire device or nanowire array device, and can generate X-ray fluorescence of 464+ / -10 and 564+ / -10 nm under the excitation of X rays. The nanomwire is expected to be widely applied to making of nanophotonics basis units, photoelectric detectors, high-energy ray detection and the like.
