Abstract

The embodiment of the invention provides a method and system for generating a single dissipative Kerr soliton pulse, and the method comprises the steps: generating a plurality of dissipative Kerr soliton pulses through a microcavity based on a first light beam transmitted to the microcavity by a laser module, and outputting a Kerr optical comb corresponding to the plurality of dissipative Kerr soliton pulses; filtering the Kerr optical comb to obtain a reference optical comb with a specified interval, and inputting the reference optical comb into the microcavity; adjusting the wavelength of asecond light beam emitted into the micro-cavity by the laser module; and controlling other dissipative Kerr soliton pulses except the target dissipative Kerr soliton pulse highly coherent with the reference optical comb in the plurality of dissipative Kerr soliton pulses to disappear, so that the microcavity outputs a target Kerr optical comb which only corresponds to the target dissipative Kerr soliton and has a specified interval. Therefore, the recovery efficiency of a single dissipative Kerr soliton pulse can be effectively improved.

Description

technical field [0001] The embodiments of the present application relate to the field of optical fiber communication, and in particular to a method and system for generating a single dissipative Kerr soliton pulse. Background technique [0002] As the demand for system capacity continues to increase, large-capacity transmission is called a key technology. Among them, one of the most common ways to increase system capacity is to increase the communication capacity of a single channel, that is, by increasing the baud rate and The modulation order can increase the single-wavelength transmission capacity to 100G bit / s, 200Gbit / s, or even 400G bit / s and higher. [0003] However, the increase of baud rate and modulation order will reduce the transmission distance, resulting in the performance limitation of single-wave high-capacity transmission. Another commonly used method is multi-channel parallel transmission. Specifically, a higher optical signal-to-noise ratio (Optical Sign...
