Synopsis Femtosecond Optical Frequency Comb: Principle, Operation and Applications by : Jun Ye
Over the last few years, there has been a convergence between the fields of ultrafast science, nonlinear optics, optical frequency metrology, and precision laser spectroscopy. These fields have been developing largely independently since the birth of the laser, reaching remarkable levels of performance. On the ultrafast frontier, pulses of only a few cycles long have been produced, while in optical spectroscopy, the precision and resolution have reached one part in Although these two achievements appear to be completely disconnected, advances in nonlinear optics provided the essential link between them. The resulting convergence has enabled unprecedented advances in the control of the electric field of the pulses produced by femtosecond mode-locked lasers. The corresponding spectrum consists of a comb of sharp spectral lines with well-defined frequencies. These new techniques and capabilities are generally known as “femtosecond comb technology. ” They have had dramatic impact on the diverse fields of precision measurement and extreme nonlinear optical physics. The historical background for these developments is provided in the Foreword by two of the pioneers of laser spectroscopy, John Hall and Theodor Hänsch. Indeed the developments described in this book were foreshadowed by Hänsch’s early work in the 1970s when he used picosecond pulses to demonstrate the connection between the time and frequency domains in laser spectroscopy. This work complemented the advances in precision laser stabilization developed by Hall.

Synopsis Sub-harmonic Generation of Frequency Combs for Spectroscopy and Quantum Optics by : Alireza Marandi
Extensive development of optical frequency combs, broadband coherent light sources with equidistant narrow spectral lines, in the near-infrared and visible has provided numerous opportunities in many fields, including frequency metrology, astronomy, attosecond sciences, and spectroscopy. The quest for extension of frequency comb techniques to the mid-infrared -- the molecular fingerprint spectral region -- continues with the promise of significant improvements in various applications related to molecular spectroscopy. This dissertation presents the results of a novel method for producing broadband mid-infrared frequency combs through sub-harmonic generation from commercially available near-infrared sources. Sub-harmonic generation occurs in a degenerate optical parametric oscillator (OPO) with salient features of (i) simplicity of the setup, (ii) low (100 mW) pump power requirement, (iii) potential for high ( 90%) conversion eciency and (vi) intrinsic phase and frequency locking to the pump. The resulting mid-infrared frequency comb is then broadened through supercontinuum generation by in-situ tapering of a chalcogenide fiber to cover the spectral range from 2.2 to 5 microns, desirable for molecular spectroscopy. Apart from its effectiveness in extension of the existing near-infrared frequency combs to the mid-infrared, sub-harmonic generation paves the way for quantum optical experiments in the frequency comb regime, because of the intriguing quantum behavior of OPOs at degeneracy. The coherence properties of such a frequency comb OPO are discussed, and the results of a novel all-optical post-precessing-free quantum random number generator are presented.

Synopsis Pulse Formation and Frequency Conversion in Dispersion-engineered Nonlinear Waveguides and Resonators by : Marc P Jankowski
Recent advances in nonlinear photonics have enabled a new class of broadband ultra-stable light sources known as optical frequency combs. These light sources have given rise to an array of new optical devices and systems, spanning applications such as spectroscopy, astronomy, remote sensing, frequency synthesis, attoscience, telecommunications, and optical clockwork. At this time, there are a number of unsolved problems within the field. Optical frequency combs are often constrained to wavelengths within the near-infrared (NIR) due to the limited variety of in mature laser gain media and host glasses, and many applications such as spectroscopy, sensing, and attoscience would benefit from the development of optical frequency combs at longer wavelength ranges such as the mid-infrared (MIR). Furthermore, the generation and stabilization of frequency combs often requires rather complicated nonlinear optical systems, which have prevented these light sources from being used outside of dedicated optics labs. This dissertation considers new approaches to frequency comb generation based on recently discovered nonlinear dynamical processes that occur in quasi-phasematched (QPM) devices with quadratic nonlinearities. A recurring theme is that the interplay of nonlinear optical effects, such as optical parametric amplification and self-phase modulation, with linear optical effects, such as dispersion, can produce qualitatively new dynamical regimes. In many cases, these dynamical regimes exhibit favorable features that potentially solve the problems discussed above. The first half of this thesis considers the pulse formation mechanisms present in optical parametric oscillators (OPOs), and discusses new operating regimes that enable the generation of MIR combs with substantially more bandwidth than the NIR comb used to drive the OPO. These devices can produce few-cycle pulses with conversion efficiencies exceeding 50% while also preserving the coherence of the frequency comb. The latter portion of this thesis studies the dynamics of femtosecond pulses in nanophotonic waveguides. Here, the geometric dispersion associated with sub-wavelength confinement be used to achieve long interaction lengths with femtosecond pulses. Using these effects we are able to achieve saturated SHG with femtojoules of pulse energy, where state-of-the-art devices previously used picojoules. In the limit of phase-mismatched SHG driven with picojoules of pulse energy we observe the formation of a coherent multi-octave supercontinuum comprised of multiple spectrally broadened harmonics. The mechanisms of spectral broadening in this system are shown to be completely unique to dispersion-engineered nanophotonic QPM devices and exhibit a number of desirable features including i) low power requirements, ii) fewer decoherence mechanisms than traditional approaches, and iii) the formation of carrier-envelope-offset beatnotes in the regions of spectral overlap between the harmonics.
