$solvecavitymod

$solvecavitymod is used to solve the optical cavity of this semiconductor device. It can be use with the command $cavitysolngrid at the same time or not.

Format

$solvecavitymod
ntotallayer nlayerleft wavelength
laythickness_1 refractive_index_1
laythickness_2 refractive_index_2
laythickness_3 refractive_index_3
...
laythickness_n refractive_index_n

Parameter Explaination

• laythickness : The layer thickness of each layer. $(\AA )$
  
• refractive_index : The refractive index of each layer you will need to setup total ntotallayer.
• nlayerleft : The number of layer on the leftside of ddcc solver. since ddcc only solve device within the semiconductor region. If there is an extra layer such as ITO and air we will need to consider them when we are solving optical cavity.
• wavelength : The wavelength frequency used in the mode calculation. $(nm)$
