  How can I see a change in the effective index vs voltage in CHARGE for LiNbO3? I browsed through the ferroelectric modulator example provided in Lumerical, it is for BiTiO3. I need to add all electrical and optical properties of LiNbO3 which I can't find on the internet. How should I proceed further?

  Hi Pratishtha,
  Unfortuanely, you would need those electrical and optical properties to be able to simulate the index vs. bias behavior of LiNbO3 in CHARGE. I would suggest you to look at some existing papers to see if you can get the values. I don't believe there is an alternative approach if we don't have those values.

  Hi Pratishtha,
  
  Lithium Niobate has been added to the material database in CHARGE in the newest release (2023 R1.2).
  
  I would suggest you to install this release and take a look. Thank you!
