研究目的
To calculate the stress field in an optical fiber with one circular stress element theoretically and derive the stress field distribution for any optical fiber with multiple stress elements based on the superposition theorem and the integration method.
研究成果
The stress field distribution formula in optical fiber with multiple stress elements has been derived based on the superposition theorem and the integration method. The stress field in the core or in the region near core can be expressed by a formula with sine or cosine function, which is critical to further explore the novel property of the stress induced optical fiber with multiple stress elements.
研究不足
The study focuses on the stress field distribution characteristics and does not address the coupling characteristics between the fundamental mode and the other higher order modes or the realization of a practical circular polarization maintained optical fiber.
