Paper Abstract

In this paper, the structure and design of a crosspoint switch using the bi-directional free-space optical interconnect system is presented. An optical model for design of the system parameters such as VCSEL beam diameter, size and apodization of the hologram, and size of the detector is given based on crosstalk analysis of the system. Impact of VCSEL wavelength variation on the system design is considered. The hologram array design and a way to improve the diffraction efficiency by a copying technique utilizing DuPont photopolymer are presented. Aberrations due to the Fourier lens in the system are calculated and ways for correction of the aberrations are discussed.
