Abstract
An all-optically generated millimeter wave carrier at 21.7GHz, 43GHz and 64.45GHz are experimentally achieved. These frequencies are realized by generating two consecutively laser wavelengths and are detecting on the 70GHz high-speed photo detector (HSPD). The initial mixing between the Brillouin pump and the second-order Stokes wavelengths is spaced by 0.178nm. This spacing, which is doubled from an inherently generated Stokes shift, is accomplished through an isolated circulation of the first order Stokes wave in the double Brillouin Stokes shifter (DSBS) built with 25-km single mode fiber. The generated millimeter carrier is measured at 21.7GHz, 43GHz and 64.4GHz achieved with BP power of 11mW, 30mW and 47mW, respectively.
