This paper demonstrates a novel technique to wirelessly injection lock a state-of-the-art 40 GHz mode locked laser and shows baseband data transmission using such a technique. This allows mode locked lasers to be used as millimeter wave modulated data sources for next generation Radio-over-Fiber systems. Binary phase shift keying data transmission rates of up to 22 Mb/s have been demonstrated for a short wireless range of 10 cm. These devices can also be used as millimeter wave phase shifters for advanced antenna beam steering systems.
