Available in PDF, EPUB and Kindle. Book excerpt: "The ever increasing demand for broader bandwidth in recent decades arises from various aspects simultaneously such as the increase in the number of users, the advent of new access methodologies, and the demand for higher access rate as well as high-quality multimedia services. Fiber optical communication technology has being developed at an unprecedented speed to meet the increasing demand. High-speed optoelectronic devices and sophisticated transmission schemes have been invented in order to fully utilize the huge transmission bandwidth provided by optical fiber. Despite the fact that different technologies exhibit their own merits and drawbacks, they share some common but critical optical components such as lasers, amplifiers, signal processing and networking devices. Innovation on these optical devices improves the optical system performance while lowering down the overall cost. Lasers that produce high repetition-rate and short duration optical pulses are essential for high-speed OTDM/WDM communication systems. The cost of a WDM transmitter could be significantly reduced if highly stable multi-wavelength laser sources could be implemented to replace the traditional DFB laser diode arrays. All-optical signal processing functions such as all-optical clock recovery are vital for the future ultra-high-speed optical transport networks as the electronic signal processing speed might be limited to a few hundred Gb/s. In this dissertation, a novel type of fiber laser - fiber optical parametric oscillator (FOPO) is analyzed and demonstrated as a simple and cost-effective solution to the above mentioned applications. It will be demonstrated that FOPOs can be configured as multi wavelength laser sources if a narrowband transmission grating filter is included in the cavity. Inherent four-wave mixing in the parametric process helps to stabilize the power distribution of the lasing wavelengths by reducing the gain competition among multiple longitudinal modes. As a result, simultaneous lasing of 129 wavelengths with 25 GHz frequency spacing is demonstrated with spectral tuning and reconfigurable features. Following the study of continuous-wave operation, actively mode-locked FOPO is studied in detail by analyzing the impact of pump requirements and cavity designs on the characteristics of the mode-locked pulses. The results provide useful guidelines for such design that high-quality optical pulses can be generated from a simple configuration. Based on a similar configuration, rational harmonic mode-locking is investigated following the harmonic mode-locking counterpart. Optical pulses generation with various repetition-rates is demonstrated through this mechanism by simply tuning the cavity length without changing the cavity configuration. Mode-locked pulses with repetition rates from 10 GHz up to 240 GHz have been generated in the experiments. Finally, the application of actively mode-locked FOPOs in all-optical clock recovery is demonstrated. A detailed investigation is performed on the 10 Gb/s operation case. The results show that this method is promising as an all-optical clock recovery solution in terms of its robustness to the input signal quality degradations over a large range, namely duty cycle from 33% to 60%, average input power from -23 dBm to 6 dBm, extinction ratio above 8.7 dB, OSNR above 27 dB, residual dispersion between -600 ps/nm to 550 ps/nm, and DGD below 48 ps. All-optical clock recovery operating at 40 Gb/s is also demonstrated following the analysis." --

Book excerpt: The papers in this volume cover the major areas of research activity in the field of ultrafast optics at the present time, and they have been selected to provide an overview of the current state of the art. The purview of the field is the methods for the generation, amplification, and characterization of electromagnetic pulses with durations from the pieo-to the attosecond range, as well as the technical issues surrounding the application of these pulses in physics, chemistry, and biology. The contributions were solicited from the participants in the Ultrafast Optics IV Conference, held in Vienna, Austria, in June 2003. The purpose of the conference is similar to that of this book: to provide a forum for the latest advances in ultrafast optical technology. Ultrafast light sources provide a means to observe and manipulate events on the scale of atomic and molecular dynamics. This is possible either through appropriate shaping of the time-dependent electrie field, or through the ap plication of fields whose strength is comparable to the binding forces of the electrons in atoms and molecules. Recent advances discussed here include the generation of pulses shorter than two optical cycles, and the ability to measure and to shape them in all degrees of freedom with unprecedented 2 21 2 precision, and to amplify them to the Zettawatt/cm (10 W /cm ) range.
