Dear Lumerical support team/users,
I am trying and evaluating the suitability of lumerical for my simulation purposes. In a first step, I am trying to reproduce literature results (paper attached). For instance, I am trying to reproduce the transmission and reflection from a slotted waveguide from Lu et al, IEEE photonics technology letters, 22, 11 (2010). I am attaching the paper and have highlighted the relevant simulation parameters. To summarize,
Structure : Ridge waveguide with etched slots
thickness of ridge: 2 micron, depth of ridge: 1.85 micron, slot width:1.1 micron, slot spacing: 7.87 micron, slot depth:1.35 micron
Aim: To calculate the reflection and transmission from the device at 1.55 micron for the fundamental TE mode and reproduce the quoted value of 0.43 and 0.4 respectively.
Method: I am using both EME and varfdtd to reproduce the results.
I am not able to get the desired results. the s-parameters obtained from the EME do not agree the transmission and reflection value quoted in the paper.
The transmission/reflection value from fdtd power monitor also do not agree with the paper.
I am new to this tool. Apologies if I have done something wrong. I am attaching both of the files (eme and fdtd).
