Abstract

In the field of optical computing, the research topic perhaps closest to widespread applications is the realization of optical board-to-board and chip-to-chip interconnections [1]. The inherent limitations of electrical interconnects regarding bandwidth and electromagnetic interference are overcome by waveguide, fiber, or free-space optics, of which the last one is generally considered to have the greatest potential. One of the basic elements is a beam splitter, which divides the incoming beam into one-dimensional or two-dimensional on/off beam arrays.
