Abstract
In this paper we have studied the optical control of transmission behaviour of λg/4 microstrip stub on a microstrip line fabricated on high resistivity silicon substrate by illuminating open end of λg/4 stub. Here, we have used two different optical wavelength sources 650nm and 850 nm to illuminate the open end of stub. An optical illumination at the end of an open λg/4 stub on a microstrip line has been shown to control the transmitted power at the design frequency which can be used as an optically controlled rf switching or attenuator and further can be used as an optically controlled narrow band matching and stub based filters. In addition to experimental measurement we have also carried out modelling of optically generated load at the end for both the wavelengths along with the simulation on Ansoft Maxwell simulator. The measurement results compare well with those predicted by a simulation carried out on the Ansoft Maxwell Ensemble for both the wavelengths.
