Paper Abstract

We report about the design of an optical intrachip clock distribution using an IR-laser diode 1 ocated at one edge of an electronic chip and 4 on-chip photoreceivers, all components connected via a reflective HOE. The high divergence angle of the laser beam and its oblique incidence onto the HOE together wfth the 4 fan-out directions require HOE-feature sizes which are in the order of the operation wavelength X0.86 tm. This study considers both multiplex and multifacet computer-generated HOEs . The pattern complexity, the respective pattern resolutions, the beam rouung abilities and the spot quality of the focused output beams are discussed. A calculation method for the estimation of the alignment tolerances is explained and the results will show that our arrangement is feasible using mounting techniques based on micromechanics in preferential etched silicon.
