Dear Lumerical support team/users,
I am trying to calculate the adiabaticity parameters of an adiabatic coupler, and the result is different with the reported result.
The reference paper is “Yung-Jr Hung, Zhong-Ying Li, Hung-Ching Chung, Fu-Chieh Liang, Ming-Yang Jung, Tzu-Hsiang Yen, and Shuo-Yen Tseng, “Mode-evolution-based silicon-on-insulator 3 dB coupler using fast quasiadiabatic dynamics,” Opt. Lett. 44 , 815-818 (2019)”.
The adiabaticity parameters is defined as
I have wrote a script to calculate the parameter accroding to definition, but I can not get the desired result. The script is attached and I will be very gratful if you can help me. Thank you very much!
