For the moment, it is only rather experimental in OSCAR but I added a new feature: generation of the sidebands from a mirror with a transverse oscillating motion. The mirror has a small amplitude displacement with respect to the laser wavelength and so a pair of sidebands will be created upon reflection (at the frequency of the oscillating mirror).

Example for a cavity similar to the arms of Advanced Virgo, only one line is added to the code to mention that the mirror is oscillating:

IM = Interface(G1,'RoC',1420,'CA',0.33,'T',0.04);

EM = Interface(G1,'RoC',1683,'CA',0.33,'T',0.1E-6);
EM = Add_Vibration(EM,'Amplitude',1E-9,'Frequency',1E0);

Arm_cavity = Cavity1(IM,EM,3000,E_input);

And then the simulations is run as usual. If we scan the oscillating frequency, we could find the classical picture that the cavity behaves as a low pass filter (outside the FSRs):

Et voilà!
