基于TRIZ与光学方法相融合的色散补偿微结构光纤的研究与设计
Research and design of dispersion-compensation micro-structured fiber based on the combination of TRIZ and optical methods
摘要
Abstract
The integration of TRIZ innovative methodology and traditional optical numerical analysis method enables the construction of a bidirectional bridge between fibre structure and fibre characteristics.And then,it presents three types of dispersion-compensating micro-structured fiber(DC-MSF)based on this connection.A discrete seven-core DC-MSF is designed by using dynamic evolution trends,resulting in the negative dispersion value of the fiber can up to-2 500 ps/(nm·km)at 1 550 nm.Additionally,a single-core polarization-maintaining DC-MSF is developed by taking advantage of the trend towards increased controllability evolution.At the wavelength of 1 550 nm,the birefringence of the core's x and y polarization modes is 8.0×10-3.The negative dispersion value is-14 230.5 ps/(nm·km)for the core's x polarization mode and-14 216.75 ps/(nm·km)for the core's y polarization mode.Furthermore,a DC-MSF filled with liquid crystals is designed through toward the metasystem evolution trend.At the wavelength of 1 550 nm,the negative dispersion value is-19 250.3 ps/(nm·km)of the fundamental mode when the liquid crystal molecule is 0°,and negative dispersion value is-16 854.7 ps/(nm·km)of the fundamental mode when the liquid crystal molecule is 90°.The proposed DC-MSFs are designed to counteract accumulated positive dispersion in fiber communication networks.关键词
