1. A wavelength cross connect, comprising:

  • at least three optical waveguides having waveguide ends arranged in a first linear array extending in a first direction perpendicular to a principal optical plane;

    a wavelength dispersive element uniform in said first direction and coupled to beams associated with each of said waveguide ends and spectrally separating wavelength components of said beams with wavelength-separated sub-beams disposed in a two-dimensional array arranged in a first waveguide direction and a first wavelength direction;

    a first set of free-space optics arranged along an optical axis extending in said principal optical plane and coupling said waveguides and said wavelength dispersive element;

    a plurality of micro electromechanical system (MEMS) mirrors arranged in a first mirror array arranged in at least a second wavelength direction and coupling at least one of said waveguides to a selected one of others of said waveguides.
