Abstract
In a multiple-axis free-space-coupled single-mode fiber-optic transmission system, such as an optical cross-connect switch, a method and apparatus are provided for the closed loop attenuation of optical beam power signals employed to align and cause dithering via MEMS mirrors which are manipulated to impose on the optical beam frequency modulation and, in particular, a time-varying set of induced mirror angles that yield a desired time history of optical power level that is modulated according to a digital code in the frequency modulation pattern.
