ABSTRACT:
A light modulator comprises a series of ribbons divided by a series of gaps. Sequences of consecutive ribbons and gaps are grouped together to form a plurality of pixels that are configured to process a respective plurality of wavelengths. The spacing from center-line to center-line of adjacent pixels is progressively increased from a reference pixel to align component pixels with their assigned wavelengths. The widths of ribbons and gaps within a particular pixel affect the polarization dependent loss of a pixel, and affect the first order diffraction angle. Ribbon widths and gap widths within successive pixels are altered to normalize polarization dependent loss and first order diffraction angles against the values associated with a reference pixel.
