We describe an optical transmission line that consists of an array of wavelength-scale optical disk resonators coupled to an optical waveguide. Such a structure leads to exotic optical characteristics, including ultraslow group velocities of propagation, enhanced optical nonlinearities, and large dispersion with a controllable magnitude and sign. This device supports soliton propagation, which ...

A large scale optical switch array based on guided-wave technology using banyan network architecture is demonstrated. Banyan network architecture is the simplest N×N network connecting a input port to all the output ports. A banyan network optical switch array serves as a base for constructing many classes of switch networks, as we propose in this report. We fabricated a 32×32 switch and measur...

Commercially available Liquid Crystal on Silicon (LCoS) Optical Phase Arrays (OPA) are capable of non-mechanically beamsteering up to ±3 degrees at 1550 nm. While the existing technology is useful for many applications such as laser communications and pulse-shaping, it is desirable to increase the steer angle and decrease the response time of the OPA. This was accomplished through a research ef...

We present an analysis of the reading capability of a novel optical pickup consisting of a single-mode and a multi-mode rectangular waveguide. According to the simulations, if one has prior information about the structure of the disk, superresolution readout could be achieved. The proposed system has the advantage to be compact and should be straightforward to be extended to arrays. The working...

Patterned illumination can be used to improve lateral resolution, provide optical sectioning, and to reduce illumination dose. For example, in Structured Illumination Microscopy (SIM), spatially periodic illumination patterns are used to double the resolution [1]. The use of a Spatial Light Modulator (SLM), such as a Digital Micro-mirror Device (DMD), gives full control over the illumination pa...

A need for active adjustment of a focal plane array (FPA) exists for space based telescopes at Sandia National Laboratories. Legacy systems relied upon manual alignment of the FPA to the optics train. The alignment was done by checking the image then adjusting the position of the FPA with shims, repeated until the desired alignment and focus were achieved. This approach has several drawbacks, i...

Designing optical components such as polarizers on substrates with high mechanical deformability have potential to realize new device platforms in photonics, wearable electronics, and sensors. Conventional manufacturing approaches that rely highly on top-down lithography, deposition and the etching process can easily confront compatibility issues and high fabrication complexity. Therefore, an a...

In this paper characterization on optical properties of silicon nanowire arrays has been made. Nanowire array has potential applications in solar cells. The effects of wire length and wavelength on the Transmission and reflection properties of nanowire arrays have been simulated. The analysis of simulated resulted has also been presented.

A synchronous multiprocessor architecture based on pipelined optical bus interconnections is presented. In this architecture the processors are placed in a square grid and are interconnected to one another through horizontal and vertical optical busses. This architecture has an effective diameter as small as 2 due to its orthogonal bus connections, and allows all processors to have simultaneous...

communications spectrum from copper cables, optical fibres, microwaves, radio and electromagnetic compatibility. Our research concentrates on optical signal processing and networks, mobile communications, microwave techniques and radiation from ICs and PCBs [1]. A considerable (and particularly interesting) part of it is related to optical beam forming for phased array antennas, using optical r...
