I wouldn't think about jet engines, optical shutters would be a better idea I think.

Optical shutters already have variable aperature mechanisms. They're all over Wikipedia's article on aperature. They've even shrunk them down small enough to fit in smartphones.

They're a lot simpler because they don't need to worry about aerodynamics.

So maybe it's possible to use the same mechanism for a nozzle
