An optically controlled continuous phase‐shifter and magnitude controller on high‐resistive silicon

Abstract

AbstractThe optically controlled phase and magnitude of a coplanar transmitted wave have been investigated, taking advantage of the benefit of silicon photo‐absorption at 843 nm. A phase‐shift of 45° has been achieved at 12 GHz while the magnitude remains constant. © 2003 Wiley Periodicals, Inc.
