Optical time stretch is a method based on the exploitation of temporal dispersion for temporally stretching information-encoded ultrashort optical pulses such that the information is detected and digitized by a slow photodetector and a slow digitizer, respectively. With pulse repetition, such a measurement can be performed at a rate of MHz to GHz, allowing for fast, continuous, real-time measurements. Since it was conceived, optical time stretch has been mainly used in data acquisition for femtosecond digitization, data compression, and spectroscopy. In recent years, the method has been further studied and advanced, enabling the observation of non-repetitive and statistically rare events on ultrashort time scales such as soliton explosions, soliton molecules, optical rogue waves, and the birth of mode-locking. Furthermore, it has led to the development of ultrafast imaging, high-throughput imaging flow cytometry, ultrafast optical coherence tomography, and ultrafast surface vibrometry. This special symposium provides a forum for introducing the fundamental principles, emerging applications, and recent advances of optical time stretch as well as for discussing its technical challenges and future perspectives.
