Title: Theoretical approach to thermal noise caused by an inhomogeneously distributed loss: Physical insight by the advanced modal expansion

Abstract

We modified the modal expansion, which is the traditional method used to calculate thermal noise. This advanced modal expansion provides physical insight about the discrepancy between the actual thermal noise caused by inhomogeneously distributed loss and the traditional modal expansion. This discrepancy comes from correlations between the thermal fluctuations of the resonant modes. The thermal-noise spectra estimated by the advanced modal expansion are consistent with the results of measurements of thermal fluctuations caused by inhomogeneous losses.

  • In metal matrix composites, temperature changes build up thermal stresses at the ceramic-metal interfaces, which result from the thermal expansion coefficient mismatch between the two phases. Depending on the relaxation mechanisms, such high stresses can degrade the mechanical properties of the composite. During mechanical spectroscopy measurements, thermal stress relaxation gives rise to an additional transient mechanical loss response. In order to interpret the dominant mechanism of stress relaxation, different models have been proposed, which relate the transient loss with interface debonding, growth of a plastic zone around the fibers, or creation and motion of dislocations. In the case of themore » magnesium-based composites, a nonlinear relation is observed between the transient loss and the measurement parameters, which cannot be explained by the existing models. In order to interpret the mechanism of stress relaxation in these composites, a new theoretical approach has been developed. The model takes into account a relaxation mechanism due to the motion of the existing dislocations. It allows one to distinguish between the case where the dislocation motion is controlled by a viscous force such as due to the dragging of solute atoms, and the case where the motion is controlled by a solid friction mechanism such as the breakaway from pinning points. In the case of the magnesium-based composites, the model allows one to conclude that the dominant mechanism of thermal stress relaxation is the motion of existing dislocations, which is controlled by a solid friction mechanism.« less
  • We describe a general framework based on modal expansion for the study of optical-frequency combs generated with monolithic whispering-gallery-mode resonators. We obtain a set of time-domain rate equations describing the dynamics of each mode as a function of the main characteristics of the cavity, namely, Kerr nonlinearity, absorption, coupling losses, and cavity dispersion (geometrical and material). A stability analysis of the various side modes is performed, which finds analytically the threshold power needed for comb generation. We show that the various whispering gallery modes are excited in a nontrivial way, strongly dependent on the value of the overall cavity dispersion.more » We demonstrate that the combs are not simply generated through a direct transfer of energy from the pumped mode to all their neighbors but rather through complex intermediate interactions. Anomalous cavity dispersion is also demonstrated to be critical for these cascading processes, and comb generation is thereby unambiguously linked to modulational instability. This theory accurately describes the emergence of spectral modulation and free spectral-range tunability in the comb. It also enables a clear understanding of the various phenomena responsible for the spectral span limitation. Our theoretical predictions are in excellent agreement with the numerical simulations, and they successfully explain the internal mechanisms responsible for the generation of hundreds of Kerr modes in monolithic whispering-gallery-mode resonators.« less
  • Authors of a recent paper [Y. K. Chembo and N. Yu, Phys. Rev. A 82, 033801 (2010)] claimed to have developed a general framework for description of nonlinear effects in whispering-gallery-mode resonators with particular focus on optical-frequency-comb generation. In this Comment we demonstrate that the author's approach contains mathematical errors affecting some of the results of the paper. Fortunately, analysis of this phenomenon using a mathematically more rigorous approach shows that the main conclusions of that paper remain intact.
  • In a Comment [Deych, Phys. Rev. A 84, 017801 (2011)] on our recent article [Chembo and Yu, Phys. Rev. A 82, 033801 (2010)] on Kerr comb generation in monolithic whispering-gallery-mode (WGM) resonators, the author claims that even though our main results ''remain intact'', the framework of our analysis contains some mathematical errors. In this Reply, we demonstrate that the author's criticisms and his alternative theory are incorrect, and that all the disagreeing claims come from the author's misunderstanding of the physical system under investigation. In particular, the main conceptual error in the Comment is the confusion between evanescent and radiativemore » coupling mechanisms for WGM resonators (in terms of Q factor, this is in our case a confusion between {approx}10{sup 9} and {approx}10{sup 2000}, respectively). This essential misconception leads for example the author to introduce a nonphysical {approx}10{sup 2000} multiplicative correction factor for the laser pump power. We show in this Reply that our WGM resonators are radiatively closed (because of the quasi-infinite radiative Q factor), so that the Mie scattering formalism proposed by Deych, which relies on radiative coupling, can only lead to erroneous results. We also show that the modal expansion approach in our original paper is appropriate, and all our approximations are physically well justified. We therefore stand by our modeling results, which are moreover in excellent agreement with the experiments reported in [Chembo, Strekalov, and Yu, Phys. Rev. Lett. 104, 103902 (2010)].« less
