Chemical Frequency Combs in Reaction-Diffusion Oscillators
Krishnesh Krishnakumar Nair, Madhurendra Mishra, Zhen Qi +1
Frequency combs, evenly spaced spectral lines locked to one fundamental frequency, are well known in optics and have also been found in phononic, magnonic, ferroelectric, and cosmo…
On the Nonlinear Sensitivity of Phononic Frequency Combs to Physical Perturbations
Madhurendra Mishra, Zhen Qi, Adarsh Ganesan
Phononic frequency combs offer a rich platform for nonlinear sensing, yet how their observable properties respond to changes in physical parameters remains poorly understood. Using…
Thermal instabilities, frequency comb formation, and temporal oscillations in Kerr microresonators
Amir Leshem, Zhen Qi, Thomas F. Carruthers +2
We analyze the consequences of dissipative heating in driven Kerr microresonators theoretically and numerically, using a thermal Lugiato-Lefever model. We show that thermal sensiti…
Existence Conditions for Phononic Frequency Combs
Zhen Qi, Curtis R. Menyuk, Jason J. Gorman +1
The mechanical analog of optical frequency combs, phononic frequency combs, has recently been demonstrated in mechanical resonators and has been attributed to coupling between mult…
Dissipative cnoidal waves (Turing rolls) and the soliton limit in microring resonators
Zhen Qi, Shaokang Wang, José Jaramillo-Villegas +5
Single solitons are a special limit of more general waveforms commonly referred to as cnoidal waves or Turing rolls. We theoretically and computationally investigate the stability…
Quasiperiodic Multicolor Solitons in Quasi-Phase-Matched Quadratic Media
Zhen Qi
We study the (1+1)-dimensional quasiperiodic multicolor solitons due to cascading quadratic nonlinear response in generalized one-dimensional quasiperiodic optical superlattice wav…
