To help us solve your issue as quickly as possible, please provide the following information:
1. What device are you trying to simulate? Include diagrams if available.
Traveling Wave Mach-Zehnder modulator explained in the link here:
2. What results are you trying to obtain? Be as specific as possible.
Variation of RF effective index as a function of doping. Group index calculation is explained in step 4 of the link.
3. Description of the problem or issue.
In step four, it is written " The values of the slab resistances and pn junction capacitance (at zero bias) are copied from step 2 and set from the script." However, I am not able to figure out which part of the script does it.
In this section,
#Set slab resistance and pn junction capacitance at zero bias
setnamed(‘n’,‘r’,6901.86); #Ohm for 1 um length in y direction
setnamed(‘junction’,‘c’,0.2098e-15); #F for 1 um length in y direction
I think resistance and capacitance are set but they are setup manually instead of exporting from step 2. Please let me know how to do it. I am new to Lumerical script so I might have missed something.
4. Lumerical product and software version.
Lumerical 2019b Mode and Charge.
5. Please attach your simulation files, including any logs.
