Abstract
We propose a new method to design and optimize a Diffractive Optical Element (DOE) that performs a quasi-synchronous optical clock distribution within a glass slab bounded onto an MCM substrate, by internal reflections. This design avoids clock skew at very high frequencies, even for non-symmetrical detector placements, and does not need any slab back side element alignments. The method is based on a phase retrieval algorithm that propagates wavefronts by the mean of two different numerical kernels between n different spatial planes. We propose also a method to optimize the detector placement on the MCM module, in order to have the DOE design to work efficiently. We have simulated the effects of typical fabrication and packaging tolerances on the performances of the overall system. A 16 phase level demonstrator is being fabricated on Thomson LCR's MCM specifications and will be tested.
