Abstract
The present invention discloses a tunable optical device. The tunable optical device includes a tuning cavity having a tuning means provided for alternately bonding to at least two different tunable optical cells each comprising a tuning membrane wherein the tuning cavity disposed near the tuning membrane for moving the tuning membrane for tuning one of the at least two tunable optical cells bonded thereon. In a preferred embodiment, the tuning cavity further includes a first electrode disposed on the tuning membrane and a second electrode disposed on a substrate supporting the tuning cavity for applying a voltage to move the tuning membrane. In a preferred embodiment, the optical device further includes an optical device control circuit connected to the tuning means for controlling and moving the tuning membrane. In a preferred embodiment, the tuning cavity further includes through hole along an optical path for an optical transmission passing through the tunable membrane for providing an interface-free and ripple-free optical path for the optical transmission. In a preferred embodiment, the tunable optical cells constitute an optical filter for bonding to the tuning cavity and tu…
