TUNABLE OPTICAL FILTER

摘要

The present invention includes a flexure mount. The tunable filter further includes an actuator coupled to the flexure mount, wherein the actuator elastically perturbs the flexure mount. The tunable filter also includes a Mach-Zehnder device (16) coupled to the flexure mount. The Mach-Zehnder device includes a first tapered coupling region (24); a second tapered coupling region (26) spaced apart from the first tapered coupling region; and a phase shift region (28) disposed in the space between the first and second tapered coupling regions.
