Complete noise characterisation of external cavity semiconductor laser hybridly modelocked at 10 GHz

To the knowledge of the authors, the first amplitude modulation (AM) and phase modulation (PM) noise measurements out to Nyquist frequency offsets for an external cavity semiconductor laser hybridly mode locked at 10 GHz are reported. The differing noise properties of a fundamentally mode-locked and a harmonically mode-locked cavity (both producing 10 GHz, pulse trains) are compared.
