Piezoelectric thin film actuator-based fiber-optic switches are introduced as low loss, high interchannel optical isolation 1 X 2 and 2 X 2 fiber-optic switches. A macroscale PZT actuator is built and tested. Preliminary results from a microscale actuator are given. Optical switch configurations and fabrication procedures are highlighted.
