Sub-harmonic generation of frequency combs for spectroscopy and quantum optics
Abstract/Contents
- Abstract
- 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.
