I am trying to model a semiconductor laser frequency stability experiment using the Pound-Drever-Hall stabilization technique.
I am trying to figure out how to model the system in SIMULINK/MATLAB.
The system consists of a semiconductor laser, electro-optic modulator, frequency reference (F.P. interferometer), associated optical components, photo-diode detector, and servo/feedback electronics.
To be useful, the model must let me analyze changes in the laser output on the order of sub hertz, in a 200 THz light source.
My initial attempt has been to try to model each component separately. The electronics are not difficult. The laser diode and optical components have proven more of a challenge.
I have been unable to find useful optics models/toolboxes and nothing on laser diodes for the MATLAB environment.
HELP! Has anyone tried to do this? How does one model a device (laser diode) that has processes going on in it at the sub-hertz to gigahertz level(electrical and physical) AND the terrahertz level (optical) as well?
Any guidance would be greatly appreciated.
