      Sir,
      I am designing all optical logic gates using two dimensional photonic crystals. In the input field properties, amplitude is set and I am calculating the contrast ratio. Is it correct or not? Otherwise, I will set the power?

      That will entirely depend on whether your definition of contrast ratio is based on power or the field. I have seen references for both definitions.

      Thank you Scott.
      Again I see different results on observation point and observation line. I am launching a a vertical input plane with 1 V amplitude at 1.55 um, when I use observation point , the result is exactly at 1.55 um, but when I use observation line I am getting at results at different wavelength. I have attached my results for your reference. Please have a look at it.
