Integrated photonics have attracted considerable attention and have been applied in both classical and quantum optics, thus fulfilling the requirements for modern optical communication experiments. Due to the remarkable flexibility in the design of optical properties, glass materials are a current focus of extensive research for their potential in integrated photonic devices. In the field of glass materials, the diverse functional micro/nanostructures directly written inside glass by ultrafast lasers have received widespread attention from researchers. In this review, the research progress in ultrafast laser-induced controllable structures in glass is briefly described with an emphasis on the transition from controllable complex physical fields to materials chemistry. The future trends of research are also prospected.
