Hello
I wrote the Fabry-Perot interferometer code in MATLAB.
But it doesn’t output well.
Please let me know if you make any mistakes.
%
% This program simulates an Fabry-Perot
%
OutputPort1 = InputPort1;
% constant
Rx = 0.45; % reflectance of translucent film
Tx = 0.45; % transmittance of translucent film
Ry = 0.9; % reflectance of reflective film
L = Parameter0; % Distance between reflective film and translucent film [m]
c = 3.0e8; % speed of light [1/m]
lambda =1.5e-6; %wavelength range [m]
f = c./lambda; %frequency[Hz]
omega = 2*pi*f; % each frequency [rad/s]
phi = 2*L*omega/c;
% calculate the optical signal
if(InputPort1.TypeSignal == ‘Optical’)
% verify how many sampled signals are in the structure
[ls, cs] = size(InputPort1.Sampled);
if( ls > 0 )
% caculate the at each signal
for counter1=1:cs
OutputPort1.Sampled(1, counter1).Signal = InputPort1.Sampled(1, counter1).Signal *((Tx^2+Rx^2)*Ry-Rx)^2 +…
(4*Rx*Ry*(Tx^2+Rx^2)*(sin(phi/2)).^2)./(((1-Rx*Ry)^2) +…
4*Rx*Ry*(sin(phi/2)).^2);
end
end
end
Hello,
Is it possible that you send me your project layout and the Matlab code to check it out? Please email them as a zip file to ahmad.atieh@optiwave.com.
The only thing that I see in the code that you are missing to define the type of signal in the Matlab code (optical, electrical, binary or Mary). You need to match that with the signal type at the input and output ports of the Matlab component in OptiSystem project layout.
Regards,
Ahmad
