I have a question about the charge_distribution (np density attribute) in the attached file in https://kx.lumerical.com/t/ring-modulator-frequency-domain-with-forward-bias-pin-junction/31927.
I know we have calculated the np density distribution for different voltage in CHARGE. But later we enable the charge_distribution and export only one active waveguide ldf file after sweep. So what’s the corresponding voltage for this ldf file? And should we change it in the INTERCONNECT section for different applied DC voltage?
