Side Illuminated Optical Fiber: Lab Manual

https://www.amazon.com/Side-Illuminated-Optical-Fiber-Manual...
This lab manual describes a series of experiments using side illuminated optical fibers. It was in 1989, 26 years ago, when AT&T Bell Labs’ scientists described, for the first time, a side illuminated optical fiber sensor. Their original device had a fluorescent cladding sensitive to oxygen and became the only known configuration for the next 16 years. These scientists recognized, very early, that this technique provided a much higher signal to noise ratio, SNR, if compared to the regular way optical fibers were used: by axial illumination. However, despite this recognition, these pioneers abandoned their own unique concept and left the least travelled road. At the end, the task of championing this neglected technique befell upon this author who started his work at the same time these researchers published their first paper. For this reason, I can also be counted among its early pioneers.Despite side illumination’s simplicity, low cost and high SNR, it did not get much attention in its first 12 years. However, it is now clear, although only in hindsight, that sensors based on side illumination could have been developed and commercially deployed in the early/mid 1990’s. For this reason, it is puzzling that very little attention was given to this technique: especially in view of the fact that, even today, axial illumination is plagued with low SNR, expensive instrumentation and low spatial resolution. So, while the scientific community kept on developing devices using axial illumination, photonics crystal fibers and Bragg gratings, side illumination languished, almost forgotten, between 1995 and 2003. Definitely, such state of affairs can only be explained in the context of Murphy’s Laws…Until 2001, side illumination was a technique that was exploited only in the US. However, little by little, interest grew in Europe, Brazil, India, Canada, South Korea, China, Australia and Hong Kong. The numbers are finally starting to paint a better picture: in the first 14 years, between 1989 and 2003, there were only 10 papers, patents, thesis and reports prepared about this technique. In the following 11 years, from 2004 to 2014, 47 new documents were added to this list: almost five times more. We now fear that there will be so much work done, that it will be difficult to track it.In addition, we are witnessing what seems to be a consistent commercialization effort of this type of device. Although in its commercial infancy, optical fiber colorimeters can make measurements from multiple cuvettes using a single detection system. If the detection system is a spectrometer, this multitude of measurements can also be made simultaneously at different wavelengths. Since only one detector is required, the larger the number of samples along the fiber, the more competitive its cost per sample. As an example, an optical fiber colorimeter that can accommodate three cuvettes is already being offered at a price that is comparable to regular colorimeters. And the future is finally looking brighter: at the beginning, side illuminated fibers used fluorescent coatings attached to expensive spectrometers and excited by massive light sources. Today’s devices are inexpensive and compact technology platforms that can also be used to make absorption, scattering and index of refraction measurements. In the addition to the optical fiber colorimeter, position and chemical sensors have also been added to this list. These devices are being used with 5 mm diameter LEDs and highly sensitive and inexpensive photodiodes that can be read by regular multi-meters. In this lab manual, we present a series of experiments that can be performed with this technology. Whether you are professional instructor or researcher, a high school, undergraduate or graduate student, you will appreciate many of the advantages and benefits of this technique that remained dormant for so many years.I hope you enjoy it!

Optical Fiber Telecommunications VIB: Chapter 5. Digital Signal Processing (DSP) and Its Application in Optical Communication Systems (Optics and Photonics)

https://www.amazon.com/Optical-Fiber-Telecommunications-VIB-...
The key question of current optical communications research is: how to maximize both capacity and transmission distance in future optical transmission networks by using spectrally-efficient modulation formats with coherent detection, and how can digital signal processing aid in this quest? There is a clear trade-off between spectral efficiency and transmission distance, since the more spectrally-efficient modulation formats are also more susceptible to optical fiber nonlinearities. This chapter illustrates the application of nonlinear backpropagation to mitigate for both linear and nonlinear transmission impairments for a range of modulation formats, at varying symbol-rates and wavelength spacings, and also by varying the signal bandwidth which is backpropagated. The basics of coherent receiver structure and DSP algorithms for chromatic dispersion compensation, equalization and phase recovery of PDM-BPSK, PS-QPSK, PDM-QPSK, PDM-8PSK, PDM-8QAM, and PDM-16QAM are reviewed and the effectiveness of the nonlinearity compensating DSP based on digital backpropagation is explored. This chapter includes a comprehensive literature review of the key experimental demonstrations of nonlinearity-compensating DSP.

Optical Fiber Telecommunications VIB: Chapter 2. Commercial 100-Gbit/s Coherent Transmission Systems (Optics and Photonics)

https://www.amazon.com/Optical-Fiber-Telecommunications-VIB-...
This chapter provides a global network service provider’s view on the technology development and product commercialization of 100-Gb/s for optical transport networks. Optical channel capacity has been growing over the past four decades to address traffic demand growth and will continue this trend for the foreseeable future to meet the ever-increasing bandwidth requirements. In this chapter, optical channels are re-classified into three basic design types. Commercial 100-Gb/s channel development experienced all three types of channel designs before eventually settling on the single carrier PM-QPSK format with coherent detection, which appears to be the optimal design in the industry. A series of 100-Gb/s channel related field trials were performed in service providers’ networks to validate the technical merits as well as business advantages of this new capacity standard before its deployment. Introduction of the 100-Gb/s channel brings new opportunities to boost fiber capacity, accommodate increases in client interface speed rates, lower transmission latency, simplify network management, and speed up the realization of next generation optical add/drop functions.

Optical Fiber Telecommunications VIB: Chapter 6. Advanced Coding for Optical Communications (Optics and Photonics)

https://www.amazon.com/Optical-Fiber-Telecommunications-VIB-...
This chapter represents an overview of advanced coding techniques for optical communication. Topics include: codes on graphs, coded modulation, rate-adaptive coded modulation, and turbo equalization. The main objectives of this chapter are: (i) to describe different classes of codes on graphs of interest for optical communications, (ii) to describe how to combine multilevel modulation and channel coding, (iii) to describe how to perform equalization and soft-decoding jointly, and (iv) to demonstrate efficiency of joint de-modulation, decoding, and equalization in dealing with various channel impairments simultaneously. Codes on graphs of interest for next-generation FEC for high-speed optical transport include turbo codes, turbo-product codes and low-density parity-check (LDPC) codes. We describe both binary and nonbinary LDPC codes, their design and decoding algorithms. We also discuss an FPGA implementation of decoders for binary LDPC codes. We demonstrate that an LDPC-coded turbo equalizer is an excellent candidate to simultaneously mitigate uncompensated chromatic dispersion, PMD, fiber nonlinearities and I/Q-imbalance. For completeness of presentation, we also provide the information capacity study of optical channels with memory.
