Abstract

An integrated array illuminator can be used not only as an optical power distributor for an array of guided-wave optic devices but also as a key element for guided-wave optical interconnections. We present a new design for an integrated-optic array illuminator with focusing waveguide diffractive doublet arrays. This integrated array illuminator allows independent optimizations of efficient and uniform optical power distribution and focusing performance. Furthermore, the device can be fabricated with all-optical lithographic technology and hence has the advantages of mass production with low cost.
