This application note shows how to envision, describe, and realize a design using fuzzy logic. It is not intended to be an introduction to fuzzy logic, but it is basic enough to be understood by designers with a cursory understanding of the subject. For those who seek an introduction to fuzzy logic, the Freescale Fuzzy Logic Educational Kit is an excellent primer. Other sources of information a...

We propose a new system for implementing quantum logic gates: neutral atoms trapped in a very far-off-resonance optical lattice. Pairs of atoms are made to occupy the same well by varying the polarization of the trapping lasers, and then a near-resonant electric dipole is induced by an auxiliary laser. A controlled-NOT can be implemented by conditioning the target atomic resonance on a resolvab...

A Field Programmable Gate Array (FPGA) with optical I/O is described. FPGAs with optical I/O can have their functionality specified in the field by downloading a control bit stream, and can be used in a wide range of applications, such as optical signal processing and optical interconnects. Our device implements six state-of-the-art Programmable Logic Arrays (PLAs) on a 2x2 mm die. The device w...

A nanoparticle undergoing light-induced transformations between structural phases with different optical properties is an inheritably bistable structure and this bistability can be used to create a resonator-free optical memory element, operating at very low power levels. We experimentally demonstrate this memory functionality using a film of gallium nanoparticles, and we present a method for d...

Reconfigurable optical directed logic circuits (RODLC) aim to perform arbitrary operations using the switch network, in which electrical signals regarded as operands are applied control propagation of light over time, and operation results obtained at output ports network form light. In this paper, a novel RODLC is proposed experimentally demonstrated by utilizing an array with prosperous mode ...

In recent years due to improvements of technology within automobile industry, design process of advanced driver assistance systems for collision avoidance and traffic management has been investigated in both academics and industrial levels. Detection of traffic signs is an effective method to reach the mentioned aims. In this paper a new intelligent driver assistance system based on traffic...

Optoelectronic integrated circuits can support thousands of integrated optical laser diodes and photodetectors bonded to a high-performance CMOS substrate, and can be used in the design of Multi-Terabit optical Local Area Networks. This paper describes the design of an integrated optoelectronic CMOS crossbar switch to interconnect approx. 128 parallel fiber ribbon optical links, each with 12 ch...

The fluorescent chemosensors 3, 5 and 7 based on thiacalix[4]arene bearing naphthyl groups have been designed and synthesized. The optical chemosensor 3 based on a thiacalix[4]arene of cone conformation behaves as "turn-on" optical chemosensor for Fe(3+) and F(-) ions. However, chemosensors 5 and 7 based on a thiacalix[4]arene of 1,3-alternate conformation demonstrate "turn-on" optical behaviou...
