Abstract

The analog modulation of RF signals on an optical carrier enables the efficient distribution and processing of wide-band signals. It is attractive to consider implementing signal processing functions in the photonic domain as well. This paper describes the design and implementation of monolithic silicon photonic devices for use in applications such as beamforming and adaptive nulling in phased array antenna systems. Low-loss fixed delay structures and slow-wave variable time delay structures are described.
