    Abstract

    A 40 GHz or 60 GHz millimeter wave phase-modulated signal is generated from a low-frequency phase-modulated optical signal injected into a distributed feedback laser diode (DFB-LD) and the frequency-multiplication factor varies from 4 to 16. The N-th modulation sideband of injection light results in wavelength locking of DFB-LD, simultaneously, the N-th modulation sideband is also amplified in the DFB-LD. Therefore, these two coherent optical fields interact in LD cavity to form stable millimeter wave phase-modulated signal. Via theoretical analyses and experimental demonstrations, the 40 GHz and 60 GHz millimeter wave phase-modulated signals are obtained by injecting 2.5, 5 and 10 GHz sine phases-modulated signal into the DFB-LD. The frequency-multiplication factor varies from 4 to 16 and the stability of the generated millimeter wave is established and proved by single sideband phase noise measurement.
