In this paper, we design a silica-cladded Germania-doped ring-core fiber (RCF) that supports orbital angular momentum (OAM) modes. By optimizing the fiber structure parameters, the RCF possesses a near-zero flat dispersion with a total variation of

We report the experimental observation of multi-bound-soliton solutions of the nonlinear Schrodinger equation (NLS) in the context of hydrodynamic surface gravity waves. Higher-order N-soliton solutions with N = 2, 3 are studied in detail and shown to be associated with self-focusing in the wave group dynamics and the generation of a steep localized ...

Active Supercontinuum Injection for Optical Parametric Chirped Pulse Amplification
The anticipant supercontinuum is a prerequisite for the pump seed generation in an optical parametric chirped pulse amplification (OPCPA) system. To achieve the anticipant supercontinuum, we develop an active method operated in a two-level control scheme
