An optical analog-to-digital converter of interferometric type
A. G. Prygunov, S. A. Chornykh, A. Yu. Tsvetkov
The paper is devoted to an urgent problem — design of multidigit high-speed analog-to-digital converters operating at frequencies up to several gigahertz and higher, and ensuring consistent resolution of the problems of development and practical application of digital adaptive antenna arrays for satellite communication systems. It is asserted that such converters have to be built based on the optical interference phenomenon. Advantages of optical interferometric converters over their electronic counterparts are discussed.
