Abstract
AbstractA novel all‐optical technique for microwave generation using photonic crystal fiber Brillouin laser is presented, and a 9.78‐GHz microwave signal generator based on the Brillouin laser is experimentally realized. The Brillouin laser is based on a fiber Fabry‐Perot cavity with fiber Bragg gratings as reflectors along with 25‐m photonic crystal fiber as Brillouin gain medium. The fiber Bragg gratings are chosen to realize low laser threshold and suppress the higher‐order Stokes waves. Predictions of numerical simulations are compared with experimental results and both are in good agreement with each other. © 2008 Wiley Periodicals, Inc.
