ABSTRACT:
A photonic bandgap device includes a first mirror region including alternating layers of different materials. A second mirror region includes alternating layers of different materials. An air gap cavity region is positioned between the first mirror region and second region. The air gap cavity changes its thickness when a voltage is applied so that the device is tuned to a particular resonant wavelength.
