局域包层模式是一种只在包层特定区域传导的模式,它的引入可极大增强光子晶体光纤对光波的调控功能。系统分析了光子晶体光纤中局域包层模式的形成机理与光学特性,阐述了局域包层模式与纤芯模式之间的耦合规律,并对包含局域包层模式的光子晶体光纤的潜在应用进行了展望。
The local cladding mode is a mode that conducts only in a specific area of the cladding. Its introduction can greatly enhance the regulation function of photonic crystal fibers on light waves. The formation mechanism and optical properties of localized cladding modes in photonic crystal fibers are systematically analyzed. The coupling rules between local cladding modes and core modes are expounded. The potential of photonic crystal fibers including local cladding modes Application prospects.
