Abstract

In this study, we investigate the impact of asymmetry and excitation wavelength on the coupling properties of soft glass dual-core optical fibers. Recent technological advancements have led to the development of high index contrast two-component soft glass dual-core fibers with sufficient symmetry, creating a new platform for nonlinear all-optical switching tasks. However, the nonlinear propagation of femtosecond pulses, which has been experimentally demonstrated, is significantly influenced by the linear optical properties of the fibers, including spectral profiles of dispersion, coupling length, and coupling efficiency. Our contribution extends beyond the novel non-destructive experimental investigation of these properties. We also conduct extensive numerical studies on the linear transmission characteristics. The findings we obtained not only deepen the understanding of the nonlinear experimental results but also provide valuable insights for development of the next generation of dual-core fibers, which will be more suitable for all-optical data processing applications.

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.
