Tunable resonant circuit comprising a RF resonator geometry disposed on an active material layer such that resonance changes when photon energy is applied

A resonant circuit comprising:

• an active material substrate having a top face;
• a busline having a single input and a single output located on the top face of the active material substrate;
• a first RF resonator geometry tuned to a first frequency, the first RF resonator geometry located on the top face of the active material substrate in electrical communication with the busline;
• and
• a second RF resonator geometry tuned to a second frequency, the second RF resonator geometry located on the top face of the active material substrate in electrical communication with the busline,
• wherein application of photon energy to the active material substrate respectively changes the resonance of the first and second RF resonator geometry at room temperatures,
• wherein the first RF resonator geometry has a first gap and the second RF resonator geometry has a second gap,
• wherein the photon energy is applied to the first and second gap of the first and second RF resonator geometry, respectively, and
• wherein the first and second RF resonator geometry comprise split ring resonators (SRRs).
