Generation of millimeter-wave in optical pulse carrier by using fiber grating

Abstract

A novel scheme is proposed to transform an optical pulse to a millimeter-wave frequency modulation pulse by using a fiber Bragg grating in radio-over-fiber system. The Fourier transformation method is used to obtain the required spectrum response function of FBG. Based on this target spectrum response function, the cases for a weak fiber grating and strong fiber grating are analyzed and the corresponding refractive index distributions are obtained. The performances of the fiber gratings are also studied by a numerical simulation method for an ultra-short pulse transmission.
