Special Section on Glass Photonics for Integrated Optics

Integrated optics is the field where photonics and glass science smartly cooperate to develop new physics, new devices, and new applications. Glass materials and photonic structures are the cornerstones of scientific and technological building in integrated optics. Photonic glasses, optical glass waveguides, planar light integrated circuits, waveguide gratings and arrays, functionalized waveguides, photonic crystal heterostructures, and hybrid microresonators are some examples of glass-based integrated optical devices that play a significant role in optical communication, sensing, biophotonics, processing, and computing.
