Summary
Bistable dark solitary waves, or "holes," exist in specific nonlinear optical systems. Numerical simulations confirm their soliton properties and explain their behavior through phase pinning.
Area of Science:
- Nonlinear optics
- Mathematical physics
Background:
- The generalized nonlinear Schrödinger equation describes light propagation in optical media.
- Solitary waves, or solitons, are self-reinforcing wave packets.
Purpose of the Study:
- To investigate the existence and properties of bistable dark solitary-wave solutions.
- To explain the dynamics and velocities of these solutions in a specific nonlinear regime.
Main Methods:
- Analytical investigation of the generalized nonlinear Schrödinger equation.
- Numerical simulations of optical switching phenomena.
- Application of the asymptotic phase pinning concept.
Main Results:
- Existence of bistable dark solitary-wave solutions (bistable holes) in the normal dispersion regime.
- Confirmation of bistable and soliton characteristics through numerical switching simulations.
- Explanation of output soliton velocities and radiation asymmetry using phase pinning.
Conclusions:
- Bistable dark solitary waves are demonstrated to exist under specific nonlinear conditions.
- Numerical simulations validate the theoretical findings and reveal complex dynamics.
- The phase pinning concept provides a framework for understanding the observed wave behaviors.
