Abstract
This paper presents an optically controlled broadband phase‐shifter using a parallel‐line coupler, that takes advantage of high‐resistivity silicon photo‐absorption at 840 nm. A continuously variable phase‐shifting of 120° is achieved at 11 GHz with Δ|S~21~| < 5 dB and with |S~11~| < −15 dB in a large frequency band (6–15 GHz). © 2005 Wiley Periodicals, Inc.
