摘要： We introduce a new all-optical mechanism that can compress the bandwidth of light pulses to absolute zero, and bring them to a complete stop. The mechanism can be realized in a system consisting of a waveguide side-coupled to tunable resonators, which generates a photonic band structure that represents a classical analogue of the Electromagnetically Induced Transparency. The same system can also achieve a time-reversal operation. We demonstrate the operation of such a system by finite-difference time-domain simulations of an implementation in photonic crystals.

摘要： We introduce a mechanically tunable photonic crystal structure consisting of coupled photonic crystal slabs. Using both analytic theory, and first-principles finite-difference time-domain simulations, we demonstrate that the transmission and reflection coefficients for light normally incident upon such structures can be highly sensitive to nano-scale variations in the spacing between the slabs. Moreover, by specifically configuring the photonic crystal structures, the high sensitivity can be preserved in spite of significant fabrication-related disorders. We expect such a structure to play important roles in micro-mechanically tunable optical sensors and filters.

摘要： Light pulses can be stopped and stored coherently, with an all-optical process that involves an adiabatic and reversible pulse bandwidth compression occurring entirely in the optical domain. Such a process overcomes the fundamental bandwidth-delay constraint in optics, and can generate arbitrarily small group velocities for light pulses with a given bandwidth, without the use of any coherent or resonant light-matter interactions. This is accomplished only by small refractive index modulations performed at moderate speeds and has applications ranging from quantum communications and computing to coherent all-optical memory devices. A complete time reversal and/or temporal/spectral compression and expansion operation on any electromagnetic field is accomplished using only small refractive index modulations and linear optical elements. This process does not require any nonlinear multi-photon processes such as four-wave mixing and thus can be implemented using on-chip tunable microcavity complexes in photonic crystals. The tuning process requires only small refractive index modulations, and moderate modulation speeds without requiring any high-speed electronic sampling.

摘要： A mold with a protruding pattern is provided that is pressed into a thin polymer film via an imprinting process. Controlled connections between nanowires and microwires and other lithographically-made elements of electronic circuitry are provided. An imprint stamp is configured to form arrays of approximately parallel nanowires which have (1) micro dimensions in the X direction, (2) nano dimensions and nano spacing in the Y direction, and three or more distinct heights in the Z direction. The stamp thus formed can be used to connect specific individual nanowires to specific microscopic regions of microscopic wires or pads. The protruding pattern in the mold creates recesses in the thin polymer film, so the polymer layer acquires the reverse of the pattern on the mold. After the mold is removed, the film is processed such that the polymer pattern can be transferred on a metal/semiconductor pattern on the substrate.

摘要： The present invention relates in part to methods for suppressing the innate immune response of a cell to transfection with an exogenous nucleic acid, to methods for increasing expression of a protein encoded by an exogenous nucleic acid by repeated delivery of the exogenous nucleic acid to a cell, and to methods of changing the phenotype of a cell by differentiating, transdifferentiating or dedifferentiating cells by repeatedly delivering one or more nucleic acids that encode defined proteins. A method is provided for extended transient transfection by repeated delivery of an in vitro-transcribed RNA (“ivT-RNA”) to a cell to achieve a high and sustained level of expression of a protein encoded by an ivT-RNA transcripts.
