Budimir Optically reconfigurable microstrip UWB bandpass filters Loughborough University 2011 untagged Mechanical Engineering not elsewhere classified 2011-02-18 17:02:23 Journal contribution https://repository.lboro.ac.uk/articles/journal_contribution/Optically_reconfigurable_microstrip_UWB_bandpass_filters/9559463 This paper presents an optically reconfigurable microstrip ultra-wideband filter. A single optical switch comprised of a silicon wafer is activated using near infra-red light to select between either a bandpass or bandstop response. With the switch in the ON state, the circuit behaves as a bandpass filter while in the OFF state, the circuit behaves as a bandstop filter in the same frequency band. The proposed filter was designed, fabricated and tested. Its performance was evaluated through simulation and measurements.
