A novel approach using a tunable optical pulse interleaver to redistribute RF power within the photodiode output spectrum for low phase noise microwave generation is proposed and experimentally investigated. By introducing a delay-controlled optical feedback loop, the tunable pulse interleaver increases signal power at selectable frequencies, enabling a high repetition rate multiplication. In contrast to conventional repetition rate multiplication schemes, the system enables the generation of tunable, low-phase-noise signals across the photodiode bandwidth. Experimental results show a successful, tunable shaping of the photodiode output spectrum, a power gain exceeding 20 dB in the millimeter wave range and thermal noise limited phase noise levels below -145 dBc/Hz at 1 MHz offset comparable to state-of-the-art RF and photonic oscillators.
