Abstract

BRIMROSE IN PHASE II WILL FURTHER DESIGN AND FABRICATE A NOVEL IN-LINE FIBER-OPTIC FREQUENCY SHIFTER WITH POTENTIAL APPLICATIONS IN LOW COST, HIGH PERFORMANCE GYROSCOPES OR ANY OTHER FIBER-OPTIC INTERFEROMETRIC SYSTEM. BRIMROSE IN WILL CONTINUE THE FURTHER DEVELOPMENT, DESIGN AND CONSTRUCTION OF HIGHER PERFORMANCE, HIGHER FREQUENCY FIBER OPTIC IN-LINE MODULATOR DEVICES. ISSUES THAT WILL BE INVESTIGATED WILL BE HIGHER FREQUENCY OF OPERATION IN THE RANGE OF 1 GHz AND HIGHER DIFFRACTION EFFICIENCIES. ALSO, SPIN-OFFS OF THIS TECHNOLOGY WILL THE EMPHASIS UPON AIR FORCE FIBER-OPTIC APPLICATIONS WILL BE EXPLORED. THE PHASE II CORE PROGRAM WILL ADDRESS TWO TYPES OF DEVICES THAT WILL BE DESIGNED AND BUILT: A) A HIGH EFFICIENCY MODULATOR WITH THE TRANSDUCER BONDED DIRECTLY INTO THE FIBER, AND B) A HIGH FREQUENCY MODULATOR WITH AN ACOUSTIC MEDIUM BETWEEN THE TRANSDUCER AND FIBER.
