1. Generation and Applications of Picosecond Pulses in High-Capacity Fiber Optic Systems
Abstract : This thesis deals with short optical pulse generation from actively mode-locked Erbium-doped fiber ring lasers (ML-EFRL) and their applications in all-optical signal processing (optical sampling and switching) and transmission experiments for high-capacity fiber optic systems. In future ultra-high bit-rate optical time division multiplexed (OTDM) systems, one of the key requirements is to develop reliable optical pulse sources that can generate high quality optical pulses.

2. Fiber optic parametric amplifiers in single and multi wavelength applications
Abstract : This thesis describes fiber optical parametricamplifiers (FOPAs) used in single- and multi-wavelength channel applications.The FOPA was operated as a pulse source in optical transmission systems at bit rates of 10-160 Gb/s. It was evaluated in terms of bit error rate after transmission with link lengths up to 650 km. READ MORE

5. Noise and Saturation Properties of Fiber Optical
Abstract : Fiber Optical Parametric Amplifiers (FOPAs) are based on a highly efficient Four-wave Mixing process in highly nonlinearfibers and have gained a lot of interest since it was shown that ahigh gain can be obtained. They are multi-functional devices thatare not only limited to amplifying signals, but their wide range ofapplicability also include wavelength conversion, pulse-generation,optical sampling and also regeneration at very high bit-rates.
