All-Optical Switches for Optical Soliton Interactions in a Birefringent Fiber

“…It plays an all-optical switching role in controlling optical solitons. [21][22][23][24][25] In this Letter, we theoretically study the coupled nonlinear Schrödinger (CNLS) equation system, analyze the principle and properties of birefringent fiber optical soliton all-optical switching, and systematically explore the influence of various parameters on birefringent optical soliton all-optical switching. The CNLS equation can be written as [26,27] 𝑖𝑞𝑗,𝑡 + 𝑖𝑐0(𝑡)𝑞𝑗,𝑥 − 𝑘2(𝑡)…”
