利用光子进行信息和图像处理的光子学被称为21世纪世纪的技术之一，其中非线性光学过程提供了频率转换和光开关的关键功能。硫属玻璃基于硫属元素S、Se和Te。这些玻璃是通过添加其他元素如Ge、As、Sb、Ga等形成的，这些玻璃是低声子能量材料，一般从可见光到红外都是透明的。掺Er、Nd、Pr等稀土元素的硫系玻璃，并因此提出了许多主动光学器件的应用。这种玻璃在光学上是高度非线性的，因此可以用于全光开关。这本书综述了硫系玻璃科学和技术的最新进展，重点是它们的非线性光学性质，供研究生、实践工程师和科学家从广泛的多学科领域，如物理、化学、电气工程和材料科学。由于世界范围内对这一领域的兴趣越来越大，一本关于这一主题的书对不同背景的研究人员将具有很大的价值。介绍了硫系玻璃及其电子、结构和光致性质。介绍了表征这些玻璃的线性和非线性光学性质的技术，并用于测量硫系玻璃的光学常数，其形式为大块、薄？我和？ber.提出了制造无源和有源器件的可能性。
Photonics, whichusesphotonsforinformationandimageprocessing, islabeled as one of the technologies of the 21st century, for which nonlinear op-cal processes provide the key functions of frequency conversion and optical switching. Chalcogenide glasses are based on the chalcogen elements S, Se, and Te. These glasses are formed by the addition of other elements such as Ge, As, Sb, Ga, etc. These glasses are low-phonon energy materials and are generally transparentfromthevisibletoinfrared. Chalcogenideglassescanbedopedby rare-earth elements such as Er, Nd, Pr, etc., and hence numerous applications ofactiveopticaldeviceshavebeenproposed. Theseglassesareopticallyhighly nonlinear and could therefore be useful for all-optical switching. This book is a review of recent progress in the science and technology of chalcogenide glasses, with an emphasis on their nonlinear optical properties, forgraduatestudents, practisingengineersandscientistsfromawidemultid-ciplinary area such as physics, chemistry, electrical engineering and material science. Since the interest in this area is growing worldwide, a book dealing with this subject will be of great value to researchers of varied backgrounds. Chalcogenide glasses and their electronic, structural, and photoinduced properties are introduced. Techniques to characterize the linear and nonlinear optical properties of these glasses are introduced and used to measure the optical constants of chalcogenide glasses in the form of bulk, thin? lm and? ber. The possibilities of fabricating passive and active devices are presented.
