Abstract
A new type of semiconductor optoelectronic device, which is called as photovaractor, was used in a self-bias mode of operation to obtain an optically-variable impedance. This approach allowed designing an optically-switched microwave band-pass filter. The use of the photovaractor in the microwave structure was investigated. The measurements of the photovaractor, the idea of the self-bias mode, and the simulations of the filter have been presented.
