Can anyone suggest how can we emulate the transfer function of an MZM ?

I also want to add that in an analog system that uses an MZM-based fiber-optic link to convey a signal without converting it to a new microwave frequency, the output fundamental signal strength is maximum when the MZM is biased at any voltage that is halfway between a maximum and minimum transmission point on the transfer function curve-a so-called “quadrature” bias point . Quadrature bias points occur when the optical phase difference at the output of the two paths in the Mach-Zehnder interferometer is an odd-integer multiple of 90 degrees. Maintaining the MZM bias at quadrature is very important in microwave systems with bandwidths wider than one octave, because only at quadrature are second-order distortion products minimized.
Check the following link for further query.

Thank you Karan for such valuable information.
second order harmonics are minimal at quadrature point as you said.
Do you know at what point are third order harmonics minimal ?
Also can you give a mathematical explanation for this ? -

Hello Jamal,
This paper may be very helpful to you. I would suggest you to go through this paper.

thanks a lot, actually i am trying to generate 64 Ghz signal using frequency octupling , Given all the values that used in a paper but somehow output is not the required one.
