This book was released on 1997 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental study of the mode-locking process in erbium-doped fiber lasers (EDFL's) operating at 1.55 microns using multiple quantum well saturable absorbers is presented. The self-starting passively mode-locked laser was constructed in a Fabry-Perot configuration using the saturable absorber as the back reflector of the cavity. Picosecond pulses that range from 14.2 to 38.8 ps were generated using a series of saturable absorbers. The pulse widths were dependent upon the optical properties of the saturable absorber used as the mode-locking element. The output power of the EDFL varied from 0.2 to 6.7 mW and was also dependent upon the saturable absorber used in the cavity. Soliton mode-locking using saturable absorbers was the mechanism responsible for the generation of the picosecond pulses by the EDFL. The long-lived carrier lifetime in the quantum wells was the primary optical property of the saturable shorter that determined the final pulse width.

This book was released on 1999 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes the development of a mode-locked erbium-doped fiber laser. Active mode-locking was achieved by modulation of a multiple quantum well (MAW) device by Stark shifting the absorption of the quantum wells. The MQW device could also act as a saturable absorber, so that the laser could be passively mode-locked. Pulses as short as 11 pico seconds were produced. The cavity was injection mode-locked at both the fundamental and second harmonic period of the cavity round-trip time.

This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: We report on the generation of conventional and dissipative solitons in erbium-doped fiber lasers by the evanescent field interaction between the propagating light and a multilayer molybdenum disulfide (MoS2 ) thin film. The MoS2 film is fabricated by depositing the MoS2 water–ethanol mixture on a D-shape-fiber (DF) repetitively. The measured nonsaturable loss, saturable optical intensity, and the modulation depth of this device are 13.3%, 110 MW/cm 2, and 3.4% respectively. Owing to the very low nonsaturable loss, the laser threshold of conventional soliton is as low as 4.8 mW. The further increase of net cavity dispersion to normal regime, stable dissipation soliton pulse trains with a spectral bandwidth of 11.7 nm and pulse duration of 116 ps are successfully generated. Our experiment demonstrates that the MoS2 -DF device can indeed be used as a high performance saturable absorber for further applications in ultrafast photonics.

Book excerpt: This report describes the results of experiments performed in various areas of material and component technology required for the development of multiple gigabit per second fiber based optical interconnect and optical communication links. First, we will summarize the development of a chromium-doped:YAG (Cr(4+): YAG) solid state laser for use in the 1500 nm transmission window of optical fiber. The Cr(4+): YAG laser produces tunable femtosecond pulses from 1488 to 1535 nm with average TEM sub 00 output powers ranging from 40 to 80 mW. The laser is mode locked using a novel saturable absorber mirror structure. The laser is also tunable from 1450 to 1574 nm in the continuous wave mode with an average TEM sub 00 output power of 600 mW at 1487 nm. Next, we will describe the synchronization of a passively mode locked erbium-doped fiber laser to an actively mode-locked fiber ring laser. Stable synchronization is obtained at injection powers of 1.5 mW. Finally, we report on the investigation of multiple quantum well saturable absorbers used to initiate mode-locking of standing wave linear cavity erbium-doped fiber lasers.

This book was released on 2012-12-06 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book summarizes the proceedings of the invited talks presented at the International Symposium of Physics and Application of Optical Solitons in Fibers held in Kyoto during November 14 to 17,1995. As a result of worldwide demand for ultra high bitrate transmissions and increased scientific interests from the soliton community, research on optical solitons in fibers has made a remarkable progress in recent years. In view of these trends, and with the support of the Japanese Ministry of Posts and Telecommunications, the Research Group for Optical Soliton Communications (ROSC), chaired by Akira Hasegawa, was established in Japan in April 1995 to promote collaboration and information exchange 'among communication service companies, industries and academic circles in the theory and application of optical solitons. This symposium was organized as a part of the ROSC activities. The symposium attracted enthusiastic response by worldwide researchers involved in this subject which has lead to the most intensive meeting that the editor ever attended. The reader will find the contents to be well-balanced among theory, experiment and technology. Although the evaluation of the contents shall naturally depend on the particular area of interest of the reader, the symposium has confirmed that the soliton based light wave transmission has achieved the best result in one channel, both in distance of transmission and in bitrate although in wavelength division multiplexed (WDM) systems, NRZ transmission has yet better result.

Book excerpt: Over the past two decades, the use of fiber lasers in engineering applications has gradually become established as an engineering discipline on its own. The development of fiber lasers is mainly the result of studies from various domains like photonics, optical sensing, fiber optics, nonlinear optics, and telecommunication. Though many excellent books exist on each of these subjects, and several have been written specifically to address lasers and fiber lasers, it is still difficult to find one book where the diverse core of subjects that are central to the study of fiber laser systems are presented in simple and straight forward way. Fiber Lasers: Fundamentals with MATLAB Modelling, is an introduction to the fundamentals of fiber lasers. It provides clear explanations of physical concepts supporting the field of fiber lasers. Fiber lasers’ characteristics are analyzed theoretically through simulations derived from numerical models. The authors cover fundamental principles involved in the generation of laser light through both continuous-wave (CW) and pulsing. It also covers experimental configuration and characterization for both CW and Q-switching. The authors describe the simulation of fiber laser systems and propose numerical modelling of various fiber laser schemes. MATLAB® modelling and numerical computational methods are used throughout the book to simulate different fiber laser system configurations. This book will be highly desirable and beneficial for both academics and industry professionals to have ample examples of fiber laser approaches that are well thought out and fully integrated with the subjects covered in the text. This book is written to address these needs.
