Abstract : To realize optical interconnects of arbitrary design, space-variant optical elements are necessary. For such applications planar holographic optical elements (HOE) offer the highest degree of flexibility and ease of production, however their diffraction-based operation gives rise to chromatic aberrations. If semiconductor lasers with poor wavelength stability are used as optical sources, the problem of chromatic aberrations can seriously limit the operation of a HOE. In this work estimates for the number of independent space-variant interconnects, their spatial tolerances and their wavelength stability are considered.
