An investigation into using hybrid mode-locked lasers to implement millimeter wave phase shift is presented. The phase shift is measured directly using a vector network analyzer enabling straightforward characterization of such systems. Both magnitude and phase of the modulation response are measured and a ldquoplateaurdquo is observed in the magnitude response which corresponds to the locking range of the system. Phase shifts of greater than 90deg are observed and such devices could have application in millimeter wave radio-over-fiber phased array antenna systems
