Abstract:
Lasers emitting visible light based on high harmonic generation (HHG) have significantly enhanced measurement capabil-ities, enabling new applications across precision metrology, attosecond science, and ultrafast time-resolved spectroscopy. This paper discusses the theoretical framework of HHG with a focus on nonlinear effects, examining in depth second-harmonic generation (SHG) and third-harmonic generation (THG) mechanisms, as well as a thermal nonlinear model for pump stability analysis. The current state of HHG within integrated optical circuits is reviewed, with a particular emphasis on its implementation in high-index doped silica glass micro-ring resonators (HDSG MRRs). We conclude by addressing future directions for optimizing these systems to expand their appli-cability in advanced photonic technologies, highlighting their potential for innovation in both applied and fundamental sciences. © 2025, Electromagnetics Academy.
