摘要： A process for making photonic crystal circuit and a photonic crystal circuit consisting of regularly-distributed holes in a high index dielectric material, and controllably-placed defects within this lattice, creating waveguides, cavities, etc. for photonic devices. The process is based upon the discovery that some positive ultraviolet (UV) photoresists are electron beam sensitive and behave like negative electron beam photoresists. This permits creation of photonic crystal circuits using a combination of electron beam and UV exposures. As a result, the process combines the best features of the two exposure methods: the high speed of UV exposure and the high resolution and control of the electron beam exposure. The process also eliminates the need for expensive photomasks.

摘要： An electro-optical switch implemented in coupled photonic crystal waveguides is disclosed. The switch is proposed and analyzed using both a finite-difference time-domain (“FDTD”) method and a plane wave expansion (“PWM) method. The switch may be implemented in a square lattice of silicon posts in air, as well as in a hexagonal lattice of air holes in a silicon slab. Switching occurs due to a change in the conductance in the coupling region between the photonic crystal waveguides, which modulates the coupling coefficient and eventually causes switching. Conductance may be induced electrically by carrier injection or optically by electron-hole pair generation. The electro-optical switch has low insertion loss and optical crosstalk in both the cross and bar switching states.

摘要： Disclosed herein is an organization of cache memory for hardware acceleration of the FDTD method. The organization of cache memory for hardware acceleration of the FDTD method provides a substantial speedup to the finite-difference time-domain (FDTD) algorithm when implemented in a piece of digital hardware. The organization of cache memory for hardware acceleration of the FDTD method utilizes a very high bandwidth dual-port on-chip memory in a particular way. By creating many small banks of internal memory and arranging them carefully, all data dependencies can be statically wired. This allows for a many-fold speedup over SRAM-based solutions and removes the burden of data dependence calculation that streaming SDRAM-based solutions must perform.

摘要： Described herein are electromagnetic traps or tweezers. Desired results are achieved by combining two recently developed techniques, 3D negative refraction flat lenses (3DNRFLs) and optical tweezers. The very unique advantages of using 3DNRFLs for electromagnetic traps have been demonstrated. Super-resolution and short focal distance of the flat lens result in a highly focused and strongly convergent beam, which is a key requirement for a stable and accurate electromagnetic trap. The translation symmetry of 3DNRFL provides translation-invariance for imaging, which allows an electromagnetic trap to be translated without moving the lens, and permits a trap array by using multiple sources with a single lens.

摘要： A method for manufacturing optical components in a three-dimensional photonic crystal lattice. A first resist (9) is coated on a substrate (10) and exposed to an e-beam (11), to produce an imaged area (12). Another resist coating is applied to thicken the resist (13) and an interference exposure (15) is used to image the result. This is developed to form periodic voids (16), which may be filled with a materials having a high refractive index to form a pattern (18 and 12) when the resist (13) is removed.

摘要： A computer hardware configuration for performing the pseudo-spectral time-domain (PSTD) method on data. The hardware configuration includes a forward fast Fourier transform (FFT) unit that calculates a forward fast Fourier transform (FFT) from the data, and a complex multiplication unit that receives the FFT-processed data and calculates a spatial derivative in the frequency domain from the FFT-processed data. The hardware configuration further includes an inverse fast Fourier transform (IFFT) unit that converts the spatial derivative in the frequency domain from the complex multiplication unit into the time domain, and a computation engine that solves a PSTD equation based upon the spatial derivative in the time domain received from the IFFT unit.

The waves are detected by modulating an optical carrier signal having a carrier signal frequency component at a carrier frequency with wave signals at one or more detection frequencies, optically removing the carrier signal frequency component from the modulated optical carrier signal, and detecting an energy level of the modulated optical carrier signal after removal of the carrier signal frequency component, the energy level indicative of the presence of the wave signals.
