Abstract :
We have experimentally studied various circuit elements in the 110-130 GHz frequency band based on dielectric image lines (DIL) that are optically controlled by IR illumination. Dielectric antennas and filters are formed by coupling the DIL to dielectric resonator pucks (DRs). IR sensitive n-type GaAs semiconductor materials are utilized and have a doping concentration of n = 2.4 × 1018 cm-3, resistance ρ = 107 Ω/cm, and mobility μ = 8500 cm2/v.s. DIL lines are excited in the dominant mode Ey11, and their time response is in the range of 10-7 s. Predicted and measured input reflection and transmission coefficients of these components are presented here in details.
