The thermo-optic effect enables precise and dynamic modulation of refractive index distributions through controllable temperature gradients in optical materials.Capitalizing on its broadband transparency,polarization independence,and non-mechanical tuning capability,this technology overcomes limitations of conventional optical modulation methods and facilitates the development of high-stability,low-power intelligent optical systems.This study systematically reviews fundamental principles,key technologies,and recent progress in thermally tunable optical devices,emphasizing the applications and achievements of two thermal modulation schemes,laser-driven and electrical-driven in tunable-focus lenses,wavefront shaping,and beam shaping.We present a comprehensive comparison of their performance characteristics and application scenarios.Additionally,this study discusses potential applications of thermally tunable optical technology in adaptive optics correction,high-resolution microscopic imaging,smart wearable devices,and precision optical fabrication,proposing theoretical frameworks and technical roadmaps for next-generation intelligent photonic devices.
