Abstract

This study investigated the enhanced dynamics of solitons in PT-symmetric couplers with nonlocal interactions. PT-symmetric waveguide arrays, characterized by balanced gain and loss, exhibit unique properties such as nonreciprocal light propagation and unidirectional invisibility. By incorporating nonlocal interactions, where the response at a point depends on the extended region’s state, we explore how these couplers achieve superior soliton stability, reduced critical power, and improved transmission efficiency. Numerical simulations reveal that PT-symmetric couplers with nonlocal terms significantly outperform conventional couplers in terms of steering dynamics, energy transfer, and phase coherence. The results demonstrate that nonlocal interactions, whether focusing or defocusing, play a crucial role in optimizing soliton propagation in PT-symmetric systems. These findings provide valuable insights for designing high-performance optical devices, highlighting the potential of PT-symmetric waveguide arrays with nonlocal nonlinearities to revolutionize optical communication technologies. This research underscores the importance of nonlocal interactions in enhancing the capabilities of PT-symmetric optical systems.

期刊介绍： Innovations in optical fiber technology are revolutionizing world communications. Newly developed fiber amplifiers allow for direct transmission of high-speed signals over transcontinental distances without the need for electronic regeneration. Optical fibers find new applications in data processing. The impact of fiber materials, devices, and systems on communications in the coming decades will create an abundance of primary literature and the need for up-to-date reviews. Optical Fiber Technology: Materials, Devices, and Systems is a new cutting-edge journal designed to fill a need in this rapidly evolving field for speedy publication of regular length papers. Both theoretical and experimental papers on fiber materials, devices, and system performance evaluation and measurements are eligible, with emphasis on practical applications.
