Methods and systems that compensate for the lateral chromatic dispersion and lateral shifts induced by the propagation through a switching/routing optical system. Utilizing the methods and systems of the present invention, an output of a switching/routing optical system that produces angularly dispersed output beams is achromatized by, first, deviating the output optical beam to a direction sufficient to induce lateral chromatic aberration of the opposite sign to that produced by the switching/routing optical system; and, then, re-deviating the deviated output optical beam to a predetermined direction, where a path length of the deviated output optical beam is a length sufficient to substantially compensate the chromatic dispersion induced by the switching/routing optical system.
