Controllable fiber-optic recirculating filters
Abstract
The concept of controlling polarization and RF filter effects within a fiber recirculating delay line filter is explored. Control techniques are theoretically proposed, simulated and verified experimentally. As a result of the robust controllability displayed by the system, a novel polarization control scheme and controller, based upon the use of optical feedback, are developed. Experimental evidence verifies the controller operation, and a complete comparison with existing controllers is included. Additionally, a new scheme for controlling RF filters is developed, and demonstrated experimentally. These studies indicate that the controlled use of optical feedback in the fiber recirculating delay line is able to control effects not normally associated with optical feedback.
