Description

technical field [0001] The invention belongs to the field of nonlinear optics research in optical communication, and specifically relates to a method and a device for generating transmittable high-power pulse trains. Background technique [0002] With the increasing transmission speed of information technology, in recent years, optical fiber communication technology has been widely valued and applied. Among them, increasing the capacity of the communication system, increasing the communication rate, and increasing the pulse power are important research directions. At present, the capacity of the communication network is improved mainly by using technical means such as wavelength division multiplexing and time division multiplexing. However, to improve the information capacity in a single channel, it is necessary to generate high-quality ultra-short pulses with a high repetition rate. However, the limited average power and low energy utilization limit the application of thes...
