Abstract
A pendulum-like member is formed in a silicon substrate. Optical fiber portions which include endface mirrors are disposed on the substrate proper and on the pendulum member. The position of the pendulum member is adjusted by applying a voltage across the member and an adjacent section(s) of the substrate thus enabling the optical length of the device to be adjusted.
