Slow Light
One of the Top Selling Physics Books according to YBP Library Services The exotic effects of slow light have been widely observed in the laboratory. However, current literature fails to explore the wider field of slow light in photonic structures and optical fibers. Reflecting recent research, Slow Light: Science and Applications presents a comprehensive introduction to slow light and its potential applications, including storage, switching, DOD applications, and nonlinear optics. The book covers fundamentals of slow light in various media, including atomic media, semiconductors, fibers, and photonic structures. Leading authorities in such diverse fields as atomic vapor spectroscopy, fiber amplifiers, and integrated optics provide an interdisciplinary perspective. They uncover potential applications in both linear and nonlinear optics. While it is impossible to account for all the captivating developments that have occurred in the last few years, this book provides an exceptional survey of the current state of the slow light field.
Slow Light
Slow Light is a popular treatment of today''s astonishing breakthroughs in the science of light. Even though we don''t understand light''s quantum mysteries, we can slow it to a stop and speed it up beyond its Einsteinian speed limit, 186,000 miles/sec; use it for quantum telecommunications; teleport it; manipulate it to create invisibility; and perhaps generate hydrogen fusion power with it. All this is lucidly presented for non-scientists who wonder about teleportation, Harry Potter invisibility cloaks, and other fantastic outcomes. Slow Light shows how the real science and the fantasy inspire each other, and projects light''s incredible future. Emory physicist Sidney Perkowitz discusses how we are harnessing the mysteries of light into technologies like lasers and fiber optics that are transforming our daily lives. Science-fiction fantasies like Harry Potter''s invisibility cloak are turning into real possibilities.
Fundamentals and Applications of Slow Light
"Slow and fast light" constitute a broad class of science and technology that can dramatically change the group index of a medium over a certain wavelength range. This thesis is composed of studies regarding both fundamental aspects and applications of slow light. The thesis starts with some discussion on two fundamental questions. The first one is how much momentum a photon carries within a slow-light medium, and what kind of force is experienced by a slow-light medium when a photon enters or leaves it. The second issue is how the noise properties of an optical field change as it propagates through a slow-light medium. The second part of the thesis deals with the applications of slow light for tunable time delays. For such applications, one of the key figures of merit is the maximum fractional delay that a slow-light element can achieve. I first present a method with experimental demonstrations for improving the maximum fractional delay using a multiple-gain-line medium. Second, I present a design with experimental demonstration for how to achieve simultaneous tunable delay and advancement using slow and fast light in a single module. I then propose a design of a digitally tunable module using channelized slow light, which can be useful for optical packet delays, etc. The third part of the thesis studies the use of slow light to enhance the performance of spectroscopic interferometers. I start with the derivation of the spectral sensitivity of two-beam and multiple-beam interferometers with slow-light media incorporated in them. I show both theoretically and experimentally that the spectral sensitivity is proportional to the group index of the medium inside the interferometers. Second, I propose and demonstrate experimentally a new type of Fourier-transform interferometer using tunable slow light. I then analyze the performance of three types of slow-light media for interferometry applications. Lastly, I present a design of an on-chip slow-light spectrometer as well as some studies on slow-light waveguides using photonic crystal structures."--Leaves ix-x
