Optical response time is an important parameter for characterizing optical materials. It defines how quickly a material responds to an external optical stimulus such as light absorption or emission. Understanding and predicting the optical response time of a material is critical to a number of fields including photonics, optoelectronics, and materials science. Accurate calculations of optical response times enable researchers and industry to optimize material design, improve device performance, and accelerate innovation in optical technologies.
