Y branch PSO(粒子群优化算法) 首先通过脚本将GDS文件导入到FDTD里 #Script to import optimized Y-Branch profile from GDSII file switchtolayout; #Specify import properties gds_filename = 'Y_branch_profile.gds'; cell_name = 'model'; layer = 1; material = 'Si (Silicon) - Palik'; z_min =...
The splitting insertion loss for the Y Branch measures the loss of signal power from the insertion of the Y Branch from the input port (port 1) to each output port (port 2 & port 3). The insertion loss is generally measured in dB. With the optimized junction for the Y branch, we se...
Y型分束器作为集成光路中的一个基本元件,其结构非常简单,也就是Y型,其主要作用是实现光的分束与合束。 1. 工作原理 Y型分束器的典型结构如下图所示,主要由三部分构成,branch区域、taper区域和直波导区域。 (图片来自文献1) 光如果从右侧直波导输入,由于结构上下对称,分支区域的两个端口中光强应该相等,相位相...
Open the python script file (varFDTD_y_branch.py) in the Lumerical environment. Running this script will import the python module y_branch_init_ that builds the simulation inputs. Alternatively, one could run this script from the command line or their python environment assuming the path to L...
We used the Finite-difference Time-domain (FDTD) method and the Particle Swarm Optimization (PSO) to generate an optimal data set as initial population for the GA. Considering an adequate population model, we demonstrate improvement in the performance for the design of a Y-branch through the ...
operation section of branch line under the Y-type mode, the waiting time of passengers on the rail transit line increases. And the shorter the operation section of the branch line, the longer the waiting time of passengers. It is unfavorable to passengers. Second, with the increase of ...
