In this paper, chirped fiber Bragg gratings (CFBGs) are proposed as signal‐phase controllers for microwave‐photonic wireless downstream fiber links. The effect of high‐order modulation optical sidebands that disturbs the output mm‐wave signal due to the chromatic dispersion induced by the gratings is studied theoretically and experimentally. The 1 st and 2 nd mm‐wave harmonics of the output signal have been measured for conventional intensity modulation and for intensity modulation with optical carrier suppression. In the last case, data transmission at 2.5 Gb/s is demonstrated through a chirped grating of 280 ps/nm dispersion in a 40‐GHz modulated link. © 2006 Wiley Periodicals, Inc.
