Stability Analysis and Research of New Optical Solitons in PT Symmetric Refractive Index Modulation Lattice

With the application of the concept of parity-time (PT) symmetric complex potential in nonlinear optics, the study of optical lattice soliton has been extended from real domain to complex domain. This project will explore the transmission behavior of new optical solitons in the PT symmetric refractive index modulation lattice. The main research contents include: Numerical research of various new types of solitons (including W type, V type, Lump type, etc.); Analysis of modulation instability of various optical solitons; Study on the interaction of various optical solitons.
