Optical lithography, the enabling process for defining features, has been widely used in semiconductor industry and many other nanotechnology applications. Advances of nanotechnology require developments of high-throughput optical lithography capabilities to overcome the optical diffraction limit and meet the ever-decreasing device dimensions. We report our recent experimental advancements to s...

Based on the optical characteristics of PLZT (Lead Lanthanum Zirconate Titanate) electro-optic ceramic, two kinds of electro-optical deflectors, triangular electrode structure and optical phased array technology, are studied in detail by using transverse electro-optic effect. Theoretically, the electro-optic deflection characteristics and mechanisms of the deflectors are analyzed; experimentall...

Optical sensors for detecting temperature and strain play a crucial role in the analysis of environmental conditions and real-time remote sensing. However, the development of a single optical device that can sense temperature and strain simultaneously remains a challenge. Here, a flexible corner cube retroreflector (CCR) array based on passive dual optical sensing (temperature and strain) is de...

In this paper, we describe a novel approach for fabricating an optoelectrochemical microring array. The array was fabricated by coating individual optical fibers of 25-microm diameter with a 1-microm layer of gold nanoparticles via electroless gold deposition. A SAM layer around the individual gold-coated imaging fibers prevented electrical contact with neighboring ring electrodes. To achieve b...

1. INTRODUCTION Integrated optical devices such as surface emitting laser array, photo detector array and OEICs promise high performance parallel processing. Although these devices have two-dimensional paral-lelism for pattern information processing, their potential capabilities are not utilized in conventional parallel processing systems. The " I/O bottleneck " between processing element (PE) ...

An optical imaging system’s resolution can often be limited by the detector array instead of the optics. We present alternate non-impulse like optical point spread functions that overcome the distortions introduced by the detector array. © 2005 Optical Society of America The optical point spread function (PSF) is often viewed as the resolution-limiting element of an imager [1]. For this reason ...
