Optoelectronic devices for unbiased microwave switching

The authors describe two simple microwave switches controlled by a weak optical beam. They are suitable for connecting microwave elements where electrical bias is not possible. Results from two devices are presented: a surface-depleted, gateless, optical FET; and a FET controlled by an integrated photovoltaic diode. Insertion losses of 3 dB and isolations of 20 dB were obtained up to 5.6 GHz with an optical power of 1 mW.<<ETX>>
