✦ Synopsis

Abstract

This work presents a wideband millimeter‐wave matching technique between active devices with very small impedances and conventionally used antennas. The matching section is an optically controlled microstrip‐taper line. Impedance transformation from 75 to 6.5 Ω is gradually obtained with minimum reflections and losses. The average transmitted power is more than 80%. The terminal impedance can be controlled by the power of the laser source, optical wavelength, or by changing the lifetime of the semiconductor substrate. © 2001 John Wiley & Sons, Inc.

## 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__~1

## Abstract This paper deals with the 3D modeling of the photo‐induced load created by a laser that illuminates a semiconductor substrate. This independent optical command allows us to change the microwave behavior of the microstrip device. We present a 3D‐equivalent microwave model for the photo‐i
