TL;DR
This paper investigates the existence, stability, and dynamics of nonlocal gap solitons in PT-symmetric optical lattices within nonlocal media, highlighting the effects of nonlocality on soliton properties through numerical simulations.
Contribution
It introduces a detailed numerical analysis of stable nonlocal PT gap solitons and explores how nonlocality influences their characteristics and stability regions.
Findings
Stable gap solitons exist in PT-symmetric lattices.
Nonlocality affects soliton power and energy flow.
Stable regions depend on the degree of nonlocality.
Abstract
We numerically study the nonlocal gap solitons in parity-time (PT) symmetric optical lattices built into a nonlocal self-focusing medium. We state the existence, stability, and propagation dynamics of such PT gap solitons in detail. Simulated results show that there exist stable gap soltions. The influences of the degree of nonlocality on the soliton power, the energy flow density and the stable region of the PT gap solitons are also examined.
