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...
