Controlled generation of high-intensity optical rogue waves by induced modulation instability

Abstract

Optical rogue waves are featured as the generation of high amplitude events at low probability in optical systems. Moreover, the formation of optical rogue waves is unpredictable and transient in photonic crystal fibers. In this paper, we put forward a method to generate high-intensity optical rogue waves in a more controlled way based on induced modulation instability, which can suppress the noise effect and hence play a leading role in the process of pulse evolution. Our numerical simulations indicate that the generation of rogue wave can be controlled when seeding at the optimal modulation frequency and the intensity of rogue wave can be enhanced with appropriate modulation depth. Further, high-intensity rogue wave can also be ejected in the fiber with a shorter propagation length by regulating the modulation depth. These results all provide a better understanding of optical rogue wave, which can contribute to the generation of tunable long-wavelength spectral components and selective excitation of mid-infrared supercontinuum.

“…A SC with flatness of 1dB and bandwidth of 1080 nm was achieved. From 2012 to 2017, many research teams have studied the SC and rogue wave generation by induced modulation instability in photonic crystal fiber [8] [9] [10] and they have pointed out the bandwidth can be increased by induced modulation instability. However, the effect of modulation instability on the coherence properties of SC has not been investigated.…”
