Special Issue Information

Dear Colleagues,

Optical frequency combs represent a revolutionary technology that allows for precise time and frequency measurement in optics, offering an unprecedented methodology for metrology, spectroscopy and frequency synthesis. In the last two decades, rapid development on both fundamentals and applications of optical frequency combs have been witnessed, and the topic ranges top hottest in the field of optics, lasers and photonics. This includes both conventional laser combs based on the mode-locked laser system, and the discovery of optical microcombs mainly based on ultra-high quality and nonlinear optical microcavities. Indeed, the latter has triggered the boom of photonic chip integrated combs in the past years, enabling miniature and chip-scale frequency metrology, and has opened up new horizons in the field of telecommunications, optical computing and LiDAR. Today, research of optical frequency combs remains highly active with emergent phenomena and new theories, as well as with new advances in related applications.

The Special Issue “Fundamentals and Applications of Optical Frequency Combs” is concerned with the groundbreaking advances, both in fundamental research and in applications, related to the topic of optical frequency combs. The areas of interest include (but are not limited to):

  • New theory and emergent phenomena on mode-locked lasers and microcombs
  • Self-referencing and frequency stabilization technique
  • Key components and materials for optical frequency comb generation
  • Optical frequency comb generation in ultra-violet, visible and mid-infrared
  • Electro-optic modulation and frequency conversion
  • Applications of optical frequency combs
  • Coherent synthesized laser combs

The generation of a quadratic soliton in a pulse-pumped microresonator has attracted significant interest in recent years. The strong second-order nonlinearity and high peak power of pumps offer a straightforward way to increase efficiency. In this case, the influence of the third-order nonlinearity effect becomes significant and cannot be ignored. In this paper, we study the quadratic soliton in a degenerate optical parametric oscillator driven synchronously by the pulse pump with third-order nonlinearity. Our simulations verify that the robustness of quadratic soliton generation is enhanced when the system experiences a perturbation from pump power, cavity detuning, and pump pulse width. These results represent a new way of manipulating frequency comb in resonant microphotonic structures. Full article
