How-to : Transmission Spectra vs Wavelength

Hi

I had attached the concept of my simulation as picture where you can understand my idea.

For obtaining Wavelength vs Transmission spectra I need to include all Refractive index (n and K values of GaAs). I had imported Refractive index values via interpolation. I had converted n and k values to Relative permitivity say GaAs_real and GaAs_imag.

Previously in Parameters I had defined Lambda = 1000 and frequency = c_const/Lambda[nm]. I had used nm in Lambda since imported (ex. GaAs_real) wavelength values as say 800 ..... without nm.

In GaAs Material properties I had defined Relative permittivity as = GaAs_real(Lambda)-j*GaAs_imag(Lambda). I think this is correct definition.

So In Parametric sweep now I can do Lambda dependent.

My Goal is to get PL spectra ( Transmission ) vs wavelength. I had placed Point in GaAs and used that as Dipole source. My target is to achieve Transmission spectra coming out from GaAs vs wavelength (say 800-1200nm). I m really confused here how-to-do. For obtaining transmission spectra do I need to use port condition or what ?
