Book excerpt: Os amplificadores a fibra dopada com érbio (EDFAs) têm se mostrado como uma alternativa bastante atraente para aumentar a capacidade de sistemas de comunicações por fibras ópticas operando na terceira janela de transmissão de fibras convencionais (lambda = 1.55 mi m). Consideráveis esforços têm sido direcionados ao aprimoramento do desempenho desses dispositivos. O potencial de aplicação em telecomunicações é grande e motiva o estudo do desempenho dos enlaces com o uso de EDFAs. A maior parte das contribuições teóricas sobre influência de amplificadores ópticos no desempenho dos receptores consiste de métodos que são fáceis de usar mas muito aproximado o que pode conduzir a estimativas bastantes imprecisas -, ou muito precisos mas de utilização extremamente difícil devido a uma complexidade inerente. São apresentados modelos para a simulação de sistemas de comunicações ópticos digitais que consideram as perdas no sinal e as distorções da forma de onda devidas ao efeito combinado do chirping do laser, da dispersão da fibra e da largura de banda finita do receptor. É proposta uma nova abordagem para o cálculo da taxa de erro do sistema e da sensibilidade, que possui a precisão e a simplicidade desejadas. O método desenvolvido considera a interferência intersimbólica (causada pelas distorções) e das contribuições de ruídos dos amplificadores, utilizando-se o método semi-analítico. Esses modelos e o método desenvolvido foram utilizados para introduzir a simulação de sistemas ópticos com EDFAs em um programa já existente de análise de sistemas. Foram realizadas simulações para avaliar as contribuições dos diversos parâmetros dos EDFAs e as implicações de algumas propriedades do sistema no desempenho total do sistema óptico. A comparação com resultados de análises rigorosas, encontrados na literatura, validou a abordagem proposta.

Download or read book Design and Analysis of a Highly Sensitive Hybrid Dispersion- Compensated Erbium-doped Fiber Amplifier written by Md Zaini Jamaludin and published by . This book was released on 2009 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Optical amplifiers have a great impact on optical communications due to their ability to amplify light along the optical path. Thus optical amplifiers have become indispensable components in high-performance optical communication links. However, while optical amplifiers are effective in mitigating link power loss problems, they are conventionally unusable and irrelevant for another major fiber optic transmission which is dispersion. Compensation of dispersion is a necessity in high speed and/or long distance links. This is separately achieved by use of a dispersion compensator which is either of fiber optics based or fiber Bragg grating based. Thus there is clear need for an integrated system which can achieve both important functions at the same time. New designs have been envisaged and achieved in this thesis. It has shown a great enhancement in performing simultaneous function in amplifying the power as well as compensating the dispersion of the signal (Hybrid). The double-pass erbium-doped fiber amplifier (EDFA) with embedded chirped fiber Brag grating and as well as other filtering technique (optical Bragg grating) have been demonstrated and investigated. It is shown through simulations and by the hardware implementation that the new design is significantly better than that of existing double pass amplifier and double pass amplifier with tunable filter. There are two levels of tests carried out in this study; device level and system (transmission) level. At the device level, the performance parameters of the new configurations are thoroughly characterized showing improvement in gain, noise figure, and the output power, considering the effects of pump power, input signal level, and input signal wavelength. The device configuration is based on double-pass amplification with a Bragg grating employed as the reflector. The grating also serves as a filter suppressing the Amplified Spontaneous Noise from the signal. At the system level, the performance parameters investigated are power sensitivity, power penalty, signal-to-noise ratio (SNR), eye amplitude, eye opening and jitter which all see a level of improvements, based on Wavelength Division Multiplexing (WDM) system. A gain as high as 53.4dB, a noise figure of as low as 5.36dB, and sensitivity of -40dBm have been achieved at the BER of 10-12 for the transmission speed of 2.5Gbps. The new hybrid amplifier provides power gain improvement of 12.5 dB and 8.4 dB for single and multi channel system. The power penalty incurred by the new hybrid amplifier for single and multi channel system are 3.5 dB and 3.2 dB respectively. Comparisons are made against the conventional double pass amplifiers and back-to-back connection.

This book was released on 2012-12-06 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this jOint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 40 (thesis year 1995) a total of 10,746 thesis titles from 19 Canadian and 144 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 40 reports theses submitted in 1995, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Book Synopsis Er/yb Co-doped Double Clad Fiber Amplifier, Its Applications and Effects in Fiber Optic Communication Systems by : Puneit Dua
Download or read book Er/yb Co-doped Double Clad Fiber Amplifier, Its Applications and Effects in Fiber Optic Communication Systems written by Puneit Dua and published by . This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Increased demand for larger bandwidth and longer inter-amplifiers distances translates to higher power budgets for fiber optic communication systems in order to overcome large splitting losses and achieve acceptable signal-to-noise ratios. Due to their unique design ytterbium sensitized erbium doped, double clad fiber amplifiers; offer significant increase in the output powers that can be obtained. In this thesis we investigate, a one-stage, high power erbium and ytterbium co-doped double clad fiber amplifier (DCFA) with output power of 1.4W, designed and built in our lab. Experimental demonstration and numerical simulation techniques have been used to systematically study the applications of such an amplifier and the effects of incorporating it in various fiber optic communication systems. Amplitude modulated subcarrier multiplexed (AM-SCM) CATV distribution experiment has been performed to verify the feasibility of using this amplifier in an analog/digital communication system. The applications of the amplifier as a Fabry-Perot and ring fiber laser with an all-fiber cavity, a broadband supercontinuum source and for generation of high power, short pulses at 5GHz have been experimentally demonstrated. A variety of observable nonlinear effects occur due to the high intensity of the optical powers confined in micron-sized cores of the fibers, this thesis explores in detail some of these effects caused by using the high power Er/Yb double clad fiber amplifier. A fiber optic based analog/digital CATV system experiences composite second order (CSO) distortion due to the interaction between the gain tilt—the variation of gain with wavelength, of the doped fiber amplifier and the wavelength chirp of the directly modulated semiconductor laser. Gain tilt of the Er/Yb co-doped fiber amplifier has been experimentally measured and its contribution to the CSO of the system calculated. Theoretical analysis of a wavelength division multiplexed system with closely spaced channels has been carried out to show that crosstalk can occur due to the four-wave mixing products generated inside the high power Er/Yb DCFA. A model for parametric amplification due to four-wave mixing has been developed and used to analyze its application for short pulse generation and high speed optical time division multiplexing.
