Скачать книгу - Distributed Feedback Laser Diodes and Optical Tunable Filters



Advances in optical fibre based communications systems have played a crucial role in the development of the information highway. By offering a single mode oscillation and narrow spectral output, distributed feedback (DFB) semiconductor laser diodes offer excellent optical light sources as well as optical filters for fibre based communications and dense wavelength division multiplexing (DWDM) systems. This comprehensive text focuses on the basic working principles of DFB laser diodes and optical filters and details the development of a new technique for enhanced system performance. Considers the optical waveguiding characteristics and properties of semiconductor materials and the physics of DFB semiconductor lasers. Presents a powerful modelling technique based on the transfer matrix method which can be used to improve the design of laser diodes, optical fibres and amplifiers. Examines the effect of the various corrugation shapes on the coupling coefficients and lasing characteristics of DFB laser diodes. Technical advice to improve immunity against the spatial hole burning effect. Extensive referencing throughout and a comprehensive glossary of symbols and abbreviations. Suitable for both introductory and advanced levels This is an indispensable textbook for undergraduate and postgraduate students of electrical and electronic engineering and physics as it consolidates their knowledge in this rapidly growing field. As a technical guide for the structural design of DFB laser diodes and optical filters, the book will serve as an invaluable reference for researchers in opto-electronics, and semi conductor device physics.

Feedback is broken – here's how to fix it to create a highly engaged workplace with high performing leaders and employees Fixing Feedback is not just another management book – it's a smart, refreshing, practical guide to feedback in the workplace. Everyone already knows how important feedback is, and we all know we should be giving it and receiving it regularly – yet we still do it poorly or avoid it entirely. This book shows you how to do it right. You'll learn what exactly constitutes useful feedback, how to deliver it effectively, how to receive it gracefully and how to use it to strengthen yourself, your team and your business. You'll learn critical communication skills that you can put into practice today, and get on track to building a «feedback culture» that results in highly engaged, highly productive employees. The way you communicate dictates how you build relationships and make decisions. It's the difference between being remarkable and being a d!ck. Poor communication is a major force driving feedback into the ground, and it can be extremely costly for the company as a whole. This book shows you how to turn the ship around by making feedback a meaningful – and welcome – part of your everyday workflow and overall company culture. Understand «remarkable feedback», and how it changes people and workplaces Self-assess your communication style and gauge the impact it has on others Deliver meaningful feedback using a set of pragmatic tools and techniques Confront the personal issues that prevent you from effectively receiving feedback Learn what organisations need to drive to create a 'feedback culture' When organisations fail to grasp the importance of investing in their people effectively, employees disengage. Building a meaningful feedback culture, on the other hand, makes your organisation a place where people want to work, want to achieve and want to be the best. It's all about effective communication. Fixing Feedback provides no-nonsense guidance toward equipping your people to succeed.

Optimize your talent by removing the obstacles in their path Capacity is a proven system for bringing the best out of your team-and yourself. Matt and Chris Johnson set the mark on how to succeed in the future with their energizing message, humorous stories and their generational differences. As the world speeds-up faster and faster, organizations and their people try to keep up. This pressure to do more with less has reached epidemic levels of concern and organizations are panicking on how to recruit, retain and attract the best talent for the future. Burnout, low engagement, and overwhelming stress are jeopardizing organizations’ ability to scale and win. As outdated performance models of the past crumble under pressure, Matt and Chris show you how to build and protect your most valuable asset—YOUR PEOPLE. What if you could beat the clock and expand your capacity by 6 hours per week? Or 11? Think about the organizational impact if your workforce were given fresh capacity to perform, lead, and grow. This book offers a clear, workable solution for organizations functioning in the real world: by paring it down to three performance pillars they must have to succeed—focus, energy, and drive. Ever organization sets initiatives, but many remain unfinished because their capacity to do so fails before it starts. This framework is different: these changes bring the type of benefits that cause transformation. Giving your people what they need makes buy-in irrelevant, and allows them to perform at their highest potential. Not only can it work, but it is the only thing that will work over the long term. By making your organization a great place to work, you retain your best talent and attract more like it. With dedicated resources, focus, sustainable effort, and comprehensive strategy, your top performers will be equipped to drive your organization to the top. Among Capacity’s Key Points: Learn what top performers need to produce their very best work Discover the biggest factor influencing your team’s FOCUS, ENERGY and DRIVE Prevent burnout and stimulate innovation by allowing your people to have a bigger container Adopt a strategy of expanding capacity to exceed your high-performance goals Deeply personal, but organizational focused. Capacity is an engaging and even life changing book Capacity is the next big paradigm shift for the future of training and development—as we shift to the world of the knowledge worker, it is not information or talent that wins, it’s is whoever has the largest capacity that will win. Capacity is your secret weapon to winning the performance war.
