Abstract
An electrostatically controlled, tunable Fabry-Perot interferometer is provided with a first, fixed mirror (4) to which a floating electrode (2) is fitted, a second, movable mirror (6) to which first and second control electrodes (8, 10) are fitted, and a resonant cavity of length d, defined by the first and second mirrors. The application of an electrical voltage between the two control electrodes operates to cause displacement of the movable mirror in relation to the fixed mirror, thereby modifying the length of the resonant cavity of the Fabry-Perot interferometer.
