This book was released on 2003 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: Widely tunable single channel fiber lasers operating in the 1550nm wavelength region are needed as laser source for applications such as wavelength-division- multiplexed (WDM) communication systems, fiber sensors, spectroscopy, and optical fiber gyroscopes. Fiber lasers are emerging as an attractive alternative technology for wavelength-selectable WDM source for direct compatibility with fiber-optic transmission medium, excellent amplifying properties of rare-earth doped fibers, rapidly continuing progress in novel fiber gain media, maturity and robustness of the laser diode pumps used, and availability of fiber-based components. The tunable laser applications of interest in this work have distinct performance requirement, which is the need for wide tunability (the ability to tune the lasing emission through a wide range of wavelengths).

This book was released on 2004 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-wavelength laser sources with constant wavelength spacing are of great interest in dense wavelength division multiplexing (DWDM) communication and sensors system. As the transmission capacity of optical communication systems is approaching a few Tb/s WDM method in recent years, multiwavelength generation technology becomes more important, considering that the complexity and the cost of the source will increase as the number od WDM channel increases. In this thesis, the design and development of a novel architecture of multi-wavelength Brilloui/Erbium fiber laser (BEFL) utilizing a linear cavity fiber loop technique is presented. Simultaneous and stable multiple wavelength lasing in a linear cavity have been achieved. The results are based completely on the experimental work. The requirement of internal feedback that is commonly used for multiple wavelengths Brillouin/Erbium fiber laser using a ring configuration is achieved by the proposed linear cavity design. This design used only a single 980 nm pump laser for its multiple wavelengths operation. Based on the design parameters namely: 980 nm pump power, Brillouin pump wavelength and single mode fiber (SMF) the performance of a novel BEFL is presented in terms of threshold power, Stokes signal peak power, number of Stokes generated , stability of the Stokes and tuningr range. Throughout this work, three lengths of SMF-fiber are used, 1.9 km, 8.8 km and 25 km. The optimization of Brillouin pump wavelength, power and Erbium gain led to a maximum possible number of Stokes. Twenty-two stable output laser lines with 10.88 GHz (0.088 nm) line spacing were obtained at 1558 nm that was the peak of Erbium-doped fiber (EDF). The injected Brillouin pump power into the 8.8 km SMF-fiber was set at 0.9 dBm and the EDF was pumped by 100 mW of 980 nm pump laser. The most efficient cascaded Brillouin Stokes operation occured at the peak of Erbium gain centered on 1558 nm. The number of Stokes decreased as the Brillouin pump increased in the highest region of Erbium gain. On the contratry, the number of Stokes was proportional to the intensity of the Brillouin pump power outside this wavelenght range. The best performance and conversion efficiency of Brillouin pump to the BEFL signal occur at the lower levels of injected Brillouin pump power. A low threshold of 4 mW pump power with 2.3 mW launched Brillouin pump into the 8.8 km of SMF-fiber at 1558 nm was obtained. The tuning range of the Stokes signal must be taken into account both the Brillouin and EDF pump power, at a fixed EDF pump power the Stokes signal can be tuned wider at a higher Brillouin pump power while higher EDF pump power produces smaller tuning range.

This book was released on 2004 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Multi-wavelength fiber lasers operating in the long-wavelength band (L-band) wavelength region are needed as laser source for applications such as wavelength-divison-multiplexed (WDM) communication systems, fiber sensors, spectroscopy and fiber optical fiber gyroscopes. Multi-wavelength fiber laser are emerging as attractive alternative technologies for wavelength-selectable WDM. They are used as source for direct compatibility with the fiber-optic transmission medium, excellent amplifying properties of rare-earth doped fibers, Brillouin gain, rapidly contiuing progress in novel fiber gain media, maturity and robustness of the laser diode pumps used and availability of fiber-based components. The multi-wavelength laser applications of interest to this work have distinct performance requirement. This requirement is the need for wide tunability (the ability to tune the lasing emissio through a wide range of wavelength). In this thesis, the design and development of a multi channel continous wave Brillouin/Erbium L-band fiber laser (BEFL), with a novel loop mirror configurations, has been studied experimentally. The design parameters of multi-wavelength fiber laser (launched pump powers , single mode optical fiber lengths and Brillouin wavelengths0, the multi wavelength Brillouin/erbium linear fiber laser configuration with bi-directional pumping is demonstrated. Throughout this work diffreent lengths of single mode optical fiber with various launched pump powers and Brillouin wavelengths have been examined to extract the optimum output performance of a BEFL. The performance of the BEFL is presented in terms of threshold pump power, output peak power, tuning range and the number od Stokes. This development fiber loop configuration exhibits considerably high performance. Twenty-four of Stokes with 10 nm tuning range and efficient output powers were obtained.

Download or read book Tunable Erbium-doped Fiber Ring Laser Using an Intra-cavity Filter written by Hicham Joseph Fadel and published by . This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Linear tuning the frequency of an erbium-doped fiber ring laser using both a Fabry-Perot filter and an electro-optic tunable filter has been experimentally demonstrated. The rate of frequency change is determined by monitoring the fringes produced by laser light transmitted through a fiber Fabry-Perot interferometer. The fiber ring laser has been tuned over a 50 nm spectral range when using the Fabry-Perot filter and a tuning rate of 16480 nm/s has been achieved. The spectral width of the laser is 0.049 nm and the nearest sidelobe to the main peak is more than 30 dB below the central lobe. When the electro-optic tunable filter is used, a spectral range of 11 nm is reached. The spectral width is 2.33 nm and is in close agreement with the filter theoretical results. The sidelobe to main peak difference is around 13 dB.
