Download or read book Advanced Performance Monitoring in All Optical Networks written by Yannis Benlachtar and published by LAP Lambert Academic Publishing. This book was released on 2010-09 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis investigates advanced optical performance monitoring approaches for future all-optical networks using the synchronous sampling technique. This allows for improved signal quality estimation, fault management and resource allocation through improved control of transmission at the physical layer level. Because of the increased transparency in next generation networks, it is not possible to verify the quality of the signal at each node because of the limited number of optical-electrical-optical conversions, and therefore new non-intrusive mechanisms to achieve signal quality monitoring are needed. The novel synchronous sampling technique can be deployed to estimate the bit error rate, considered an important quality measure, and hence can be utilised to certify service level agreements between operators and customers. This method also has fault identification capabilities by analysing the shapes of the obtained histograms. Each impairment affects the histogram in a specific way, giving it a unique shape that can be used for root cause analysis.

Book excerpt: Although the theory and principles of optical waveguides have been established for more than a century, the technologies have only been realized in recent decades. Optical Waveguides: From Theory to Applied Technologies combines the most relevant aspects of waveguide theory with the study of current detailed waveguiding technologies, in particular, photonic devices, telecommunication applications, and biomedical optics. With self-contained chapters written by well-known specialists, the book features both fundamentals and applications. The first three chapters examine the theoretical foundations and bases of planar optical waveguides as well as critical optical properties such as birefringence and nonlinear optical phenomena. The next several chapters focus on contemporary waveguiding technologies that include photonic devices and telecommunications. The book concludes with discussions on additional technological applications, including biomedical optical waveguides and the potential of neutron waveguides. As optical waveguides play an increasing part in modern technology, photonics will become to the 21st century what electronics were to the 20th century. Offering both novel insights for experienced professionals and introductory material for novices, this book facilitates a better understanding of the new information era—the photonics century.

Download or read book Integrated Optical Signal Processing Based on Optical Waveguides and Wavefront engineered Planar Devices written by Yuewang Huang and published by . This book was released on 2014 with total page 159 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis is dedicated to the investigation of optical signal processing in integrated photonic platforms. In particular, I developed novel devices and techniques based on silcon-on-sapphire (SOS), silicon-on-insulator (SOI) and silicon nitride (SiN) waveguides, as well as plasmonic metasurfaces and dielectric gratings based nanophotonic wavefront-engineered planar devices. Using these devices, several applications of telecommunication wavelengths and mid-IR wavelengths are presented. The first part of the thesis investigates novel devices based on SOS and SiN technology and optical signal processing by using these devices. The fabrication techniques of both SOS and SiN waveguide are introduced with main focusing on the deposition of the guiding material (Si and SiN). Fabrication of SiN channel waveguides was pursued in the context of providing a guiding channel for optical leaky wave antenna (OLWA). A new technique of fabricating SiN waveguide with conventional optical lithography was also discussed. The fabricated SiN waveguides have a propagation loss of 0.8dB/cm and nonlinear refractive index of n2=1.39 710−19m2/W. Then, a gas sensor based on mid-IR evanescent absorption in SOS waveguide was proposed. Strip, rib and slot waveguides were designed for optimized interaction with the gas. A case study of CO2 detection based on its mid-IR absorption peak at ~4.23[mu]m can achieve a resolution of 2ppm. To further improve the sensing performance, a new scheme of indirect detection of mid-IR signal was proposed. One of the main challenges in the field involves the detection of mid-IR signal at room temperature. I developed an indirect detection system. Mid-IR signal was first converted to the near-IR wavelength through wavelength conversion in a SOS waveguide and then indirectly detected with high-performance telecommunication detectors. The signal-to-noise ratio (SNR) could be improved by 40dB compared to direct detection using mid-IR detectors. The SNR improvement is highly dependent on the conversion efficiency and bandwidth of the wavelength conversion process. To enhance the efficiency and bandwidth, quasi-phase-matching in SOS and SOI waveguides was investigated. By alternating the waveguide sections with opposite dispersion periodically, efficiency can be enhanced by 50dB and bandwidth can be broadened by 2x.The second part of the thesis focused on the design and fabrication of two types of wavefront-engineered planar devices. The first type is a blazed grating based on phase-gradient gap-plasmon metasurface. 75.6% power efficiency with ~0.4°/10nm spatial dispersion has been measured. The fabricated device has been tested in a dispersive imaging system, achieving
