摘要
用有效折射率法 ,采用近轴近似和波导模场分布的高斯近似 ,简化了阵列波导光栅( AWG)器件的设计过程中繁杂的计算 ,且保证了器件的性能指标 .给出了设计思路 ,并给出了 1× 8路、中心波长为 1 550 .9nm,波长间隔为 1 .6nm的 AWG波分复用
A simple design process is presented by using the effective refractive index method,paraxial approximation and the Guass function approximation of the diffraction pattern from the individual waveguide.This method avoids large amount of numerical calculations.A design procedure is given,as well an AWG multiplexer designed for an example,which is of 8 channels,with a center wavelength is 1550 9nm and wavelength spacing 1 6nm.
