Abstract

We propose a novel technique to achieve optical frequency up-conversion in millimeter wave band without any local microwave oscillator. It is hard to directly get mm band carrier frequency because the efficiency of the mode-locking decreases as the carrier frequency increases. Thanks to the dynamic charge carrier density response during the injection locking of Febry-Perot Laser diode (FP-LD), the wavelength of the leading part of carrier will be red-shifted while that of falling part will be blue-shifted. With a suitable negative dispersion device, the carrier will be pulse compressed and the 2nd harmonic of the carrier will be greatly enhanced. Thus it makes the RoF frequency up-conversion in mm band feasible. By utilizing injection locking of Febry-Perot Laser diode, a suitable negative dispersion device and polarization interferometer, a 2.5Gb/s baseband signal is frequency up-conversed to a subcarrier modulation signal at 30.8GHz.
