Advanced Photonic Technologies: From Light Sources and Nonlinear Optics to Sensing Applications

Dear Colleagues, 

Photonics technology, fundamental to the information age, is revolutionizing the future of scientific research and industrial innovation with unprecedented depth. From high-speed global communications and precision medical diagnostics to quantum computing and advanced manufacturing, cutting-edge photonic technologies are not only crucial for scientific and technological progress but also for addressing major global challenges in energy, environment, and health. This Special Issue aims to compile the latest groundbreaking research in this field, establishing a platform for exchanging ideas, from fundamental physical exploration to state-of-the-art technological applications. It seeks to demonstrate how photonics, through the integrated technology chain of light source innovation, nonlinear control, and sensing applications, continuously expands our capacity to understand and reshape the world. We invite researchers from across the world to contribute original research articles and comprehensive reviews that cover theoretical and materials-, device-, and systems-level applications. We hope that this Special Issue fosters interdisciplinary cross-fertilization and advances photonic technologies to new heights.

This Special Issue focuses on the core components of the advanced photonics technology ecosystem, with topics of interest including, but not limited to, the following areas:

(1) Advanced Light Sources and Laser Technologies

• Novel high-power, narrow-linewidth, ultrafast, and tunable lasers;
• On-chip micro-lasers and photonic integrated circuits;
• The development of novel laser sources, such as quantum dot lasers and fiber lasers.

(2) Nonlinear Optical Processes and Devices

• Nonlinear frequency extension techniques, including harmonic generation, frequency conversion, and parametric oscillation;
• Nonlinear effects and their applications, such as stimulated Raman scattering and four-wave mixing;
• Novel nonlinear optical materials and devices based on metasurfaces, photonic crystals, and two-dimensional materials.

(3) Biophotonics and Advanced Imaging

• Multiphoton microscopy, super-resolution imaging, coherent anti-Stokes Raman scattering (CARS) imaging, etc.;
• Deep-tissue imaging techniques, including optical coherence tomography and photoacoustic imaging;
• Novel optical imaging methods for disease diagnosis, cell biology, and neuroscience;

(4) High-Precision Fiber and Spectroscopic Sensing:

• Applications of photoacoustic spectroscopy sensing in environmental monitoring, industrial process analysis, and medical breath diagnostics;
• High-sensitivity detection techniques, such as cavity-enhanced absorption spectroscopy and laser-induced breakdown spectroscopy;
• Novel optical fiber sensors for trace gas detection, chemical analysis, and substance identification.
