Optical Fiber Telecommunications V (A&B) is the fifth in a series that has chronicled the progress in the research and development of lightwave communications since the early 1970s. Written by active authorities from academia and industry, this edition not only brings a fresh look to many essential topics but also focuses on network management and services. Using high bandwidth in a cost-effective manner for the development of customer applications is a central theme. This book is ideal for R&D engineers and managers, optical systems implementers, university researchers and students, network operators, and the investment *** (A) is devoted to components and subsystems, including: semiconductor lasers, modulators, photodetectors, integrated photonic circuits, photonic crystals, specialty fibers, polarization-mode dispersion, electronic signal processing, MEMS, nonlinear optical signal processing, and quantum information technologies. Volume (B) is devoted to systems and networks, including: advanced modulation formats, coherent systems, time-multiplexed systems, performance monitoring, reconfigurable add-drop multiplexers, Ethernet technologies, broadband access and services, metro networks, long-haul transmission, optical switching, microwave photonics, computer interconnections, and simulation *** SketchesIvan Kaminow retired from Bell Labs in 1996 after a 42-year career. He conducted seminal studies on electrooptic modulators and materials, Raman scattering in ferroelectrics, integrated optics, semiconductor lasers (DBR , ridge-waveguide InGaAsP and multi-frequency), birefringent optical fibers, and WDM networks. Later, he led research on WDM components (EDFAs, AWGs and fiber Fabry-Perot Filters), and on WDM local and wide area networks. He is a member of the National Academy of Engineering and a recipient of the IEEE/OSA John Tyndall, OSA Charles Townes and IEEE/LEOS Quantum Electronics Awards.

To investigate the creep and instability properties of a cemented gangue backfill column under a highstress area,the uniaxial compression creep tests were conducted by single-step and multi-step loading of prismatic samples made of cemented gangue backfill material(CGBM)under the high stressstrength *** creep damage was monitored using an electrical resistivity device,ultrasonic testing device,and acoustic emission(AE)*** results showed that the CGBM sample has a creep hardening *** creep failure strength(CFS)is slightly larger than the uniaxial compressive strength(UCS),ranging in ratio from 108.9%to 116.5%.The instantaneous strain,creep strain,and creep rate increase with increasing stress-strength ratio in the single-step loading creep *** instantaneous strain and creep strain decrease first and then increase during the multi-step loading creep *** axial creep strain of the CGBM column can be expressed by the viscoelastic-plastic creep *** instability is caused by the accumulation of strain energy under multi-step loading and the continuous lateral expansion at the unconstrained middle position during the creep *** creep stability of a CGBM column in a high-stress area can be monitored based on the variation of electrical resistivity,ultrasonic pulse velocity(UPV),and AE signals.

Fiber optics underpins the communications infrastructure for the information society today. Cables consisting of hair-like fibers speed data around the globe in the form of rapid pulses of light. Modern telecom infrastructure facilitating high-speed broadband internet would not be possible without it. Rapid progress of advanced modulation formats, coding, optical amplification, coherent detection, and digital signal processing has made significant impact in the field of optical communications.

Rump Session 1:Strategic Research and Engineering Innovation

Rump Session 1:Strategic Research and Engineering Innovation

引用

国际纳光电子学研讨会

作者： tingye.Li AT&T Labs(Retired) USA

＜正＞Advances in telecommunication and information technologies are fueled by engineering innovations arising from strategic research. Strategic research may be defined as that mission-oriented research which pursues specific and realistic goals leading to practical applications. Prior to the telecom bubble of year 2000,much of the strategic research was conducted in the industry,while the academe pursued largely fundamental research leading to knowledge acquisition. Globalization and competition led to the dissolution of much of the fundamental and long- range strategic research in the industry,leaving the work to be carded out in the academe supported by government agencies. This rump session will examine the present global research environment in IT and telecom industries, addressing issues relating to industrial and societal needs,incremental and disruptive applications,funding processes and efficiencies,long-range strategic visions,and other matters of cogent interest.

全国第十三次光纤通信暨第十四届集成光学学术会议

作者： tingye.Li AT&T Labs-Research (Retired) Boulder, Colorado 80304, USA

Optical fiber communications, introduced commercially about 30 years ago, has over the years brought about revolutionary changes in the telecommunications industry, ranging from network infrastructure and operations, to the management and economics of supplying bandwidth. The deployment of amplified multi-channel WDM systems has uniquely evoked substantial improvement in the unit cost ($/Gb/km) of equipment and operations, and more notably, unprecedented enhancement in transmission capacity. Continuing advances in lightwave technologies help enable service providers to evolve their networks and to improve and sustain their economic well-being. This talk will present perspectives on transformations in optical fiber communications, compare past and present technology development trends, discuss paradigm shifts due to Internet traffic demand, consider service providers’ dilemmas, examine technological advances that provide strategic, economic and operational advantages, and note promising fields of research that offer potential impact.

卫星导航定位是测绘工作中应用最广泛的技术之一,"GPS测量原理与应用"课程也一直是测绘工程专业本科生的主干课,具有理论深、更新快、知识面广、实践性强等特点,对教与学都有很高的要求。本文分析了笔者在广东工业大学与合肥工业大学讲授该课程过程中所发现的一些问题,包括教材更新慢、内容抽象、授课方式以"填鸭式"为主、实践时间不足、程序设计能力弱等。针对这些问题,笔者在教学过程中将学术研究前沿与课本知识有机结合,采取教师授课、学生自主学习交流、穿插专家学术讲座等教学形式,完善实验仪器设备和校内外实习基地,协调与其他课程的内容安排等措施,从教学的内容和模式等方面进行了改革和创新。
