Deyasi Arpan, Maity Avisek, Karmakar Arka PMQW based Optical Filter Design with Semiconductor Heterostructure

Inside the two covers, transmittivity of photonic multiple quantum well-constructed using suitable semiconductor heterostructure composition is numerically analyzed by transfer matrix technique. From the result, bandwidth of the proposed photonic bandpass filter is computed under both polarized and normal incidence, and results are compared for identical structural parameters. Conventional photonic crystal is made by SiO2/air combination, and results are also calculated for it. Comparative study reveals the fact that our proposed heterostructure composition is far suitable for bandpass filter design when optical communication at 1550 nm is of prime concerned, and better tuning of bandwidth is also possible. Analysis for photonic crystal fiber is made with SiO2-Air composition for performance study through V-parameter, cladding index and effective mode profiles. Comparative analysis is carried out between these two material compositions which reveal that proposed heterostructure may provide better performance as filter and also efficient in guiding electromagnetic wave. Results will paly critical role in designing optical bandpass filter in future photonic integrated circuit.

Raz Oded Photonic Processing of Microwave Signals

Photonic processing of microwave signals aims to utilize the many advantages of optical waveguides and devices such as their >THz bandwidth, high EMI tolerance and low weight and volume over traditional microwave devices. These advantages can be best used in the demanding environment of radar systems and even more so in airborne systems. Many radar systems use electronically steered antenna in order to search for targets. raditional phase scanning arrays are limited in there fractional bandwidth and so time scanning arrays are required for large arrays used by radars emitting large bandwidth signals (either very short or phase coded pulses). Due to the advantages described above, it is only natural that photonic True Time Delays (TTDs) will find their way into future radar systems. Such Photonic TTDs have superior microwave characteristics over traditional microwave devices as will be extensively demonstrated throughout this research work. In this research work both continuous and discrete photonic TTDs were explored showing their potential use for application in radar systems an in particular for wide band width systems

Applications which use wireless sensors are increasing in number. The emergence of wireless sensor networks has also motivated the integration of a large number of small and lightweight nodes which integrate sensors, processors, and wireless transceivers. Existing books on wireless sensor networks mainly focus on protocols and networks and pay little attention to the sensors themselves which the author believes is the main focus. Without adequate knowledge of sensors as well as how they can be designed, realized and used, books on wireless sensor networks become too theoretical and irrelevant. The purpose of this book is to intimately acquaint readers with the technique of sensing (resistive, capacitive, inductive, magnetic, inertial, etc.) and existing sensor technologies. It also discusses how the sensors are used in a wide application domain and how new sensors can be designed and used in a novel way.

Pietro Salvo Wearable Technologies for Sweat Rate and Conductivity Sensors. Design and Principles

Wearable sensors present a new frontier in the development of monitoring techniques. They are of great importance in sectors such as sports and healthcare, as they permit the continuous monitoring of physiological and biological elements, such as ECG and human sweat. Until recently, this could only be carried out in specialized laboratories in the presence of cumbersome, and usually, expensive devices. Sweat monitoring sensors integrated onto textile substrates are not only part of a new field of work but, they also represent the first attempt to implement such an innovative idea on a system which will be worn directly on the body. The objective of this book is to present possible designs and technologies of low cost wearable sweat rate and conductivity sensors integrated onto a textile. The first chapter deals with a preliminary introduction on sweat production and composition, and the applications of wearable devices. Further, the second chapter describes the conductivity sensor, i.e. the geometry, materials and the coupling which includes a temperature sensor for precise measurements are discussed. This is followed by a chapter on the sweat rate sensor, and the technologies employed to fabricate it. Sensors that are based on a) conductive yarns coated with hydrophilic polymers, b) conductive polymer fibres, c) hydrophilic polymers between conductive fabrics and d) humidity sensors are described in detail. Finally, the last chapter provides a study of sweat production in di...

Molecularly imprinted polymers (MIPs) are an important functional material because of their potential implications in diverse research fields. The materials have been developed for a range of uses including separation, environmental, biomedical and sensor applications. In this book, the chapters are clustered into two main sections: Strategies to be employed when using the affinity materials, and rational design of MIPs for advanced applications. In the first part, the book covers the recent advances in producing MIPs for sample design, preparation and characterizations. In the second part, the chapters demonstrate the importance and novelty of creation of recognition imprinted on the materials and surfaces for a range of microbial detection sensors in the biomedical, environmental and food safety fields as well as sensing human odor and virus monitoring systems.

Murray W. McCutcheon Nonlinear Optics in Photonic Srystal Microcavities

In the last decade, there has been a rapid growth in research on the wavelength-scale design of materials to control optical information. Photonic crystal microcavities allow the trapping of optical fields in near fundamentally-small volumes, with many diverse applications such as filtering and switching. To effect conditional operations in a microcavity-based device, the nonlinear optical properties of multi-mode microcavities must be explored, and this theme forms the focus of this book. A resonant scattering technique is developed to si­multaneously excite multiple microcavity modes with a short-pulse laser. Using this method, the second-order nonlinear properties of InP-based microcavities are investigated, revealing sum-frequency mixing between two modes. An ultrafast pump-probe experiment is then described which demonstrates all-optical switching and frequency conversion in a silicon microcavity.This book should be a significant resource for experimentalists in the nanophotonics community, as it contains comprehensive chapters discussing each of the techniques of sample nanofabrication, numeri­cal modeling, and optical spectroscopy that are instrumental to this work.

Ninad Gondhalekar Controlling the atmospheric turbulence, microPIC programming

Bachelor Thesis from the year 2013 in the subject Computer Science - Programming, Northumbria University, course: BEng. Electrical and Electronic Engineering (Hons.), language: English, abstract: Chamber is used to study atmospheric turbulence effects on FSO signals and this experiment is done inside the laboratory to avoid the interference of sunlight light and also it is hard to create turbulence outside laboratory as outside temperature and pressure will affect the turbulence created inside this chamber. This project is all about controlling all parameters (temperature, pressure, humidity) using sensors, fans, thermistors through embedded circuit.As observed from previous work, high end microPIC (PIC18 series) although it has many functionality and large program memory size, it is hard to control all sensors, fans, thermistor using 1 PIC1866K80, So in this project mid-range PIC (PIC16 series) are used to control sensors, fans and thermistors. In this project, temperature, humidity, pressure sensors are controlled by different microcontrollers and taking their reading to manage the performance of PWM fans and thermistors inside the chamber. These components are very important to configure and monitor the atmospheric condition inside the chamber. This project focuses on the use of PIC16 family microcontrollers to be programmed in C language or in assembly to control all sensors, fans and thermistor and build PCB layout. In this project, Rs-232 or Com port will be used as an ...
