NOVELTY - The utility model claims a tunable phase-shifted fibre grating based optical carrier microwave generator of the graphene, comprising electro-optic phase modulating a waveguide (1), the graphite film (2), a graphite film electrode (P1), graphite film electrode P2. A graphene thin film electrode (P1) and graphite film electrode (P2) is graphite film (2) on the loading electric field caused by the graphene thin film by changing the electric field (2) of the electro-optic phase modulating a waveguide (1), a wave guide to modulate, that is to change the input light carrier microwave field by changing the phase modulation of a frequency interval to change the input light carrier microwave field by changing the amplitude modulation electric field to centre frequency. A microwave generator can solve the problem that the current optical carrier centre frequency microwave generator can not be adjusted, which effectively use the frequency spectrum resource.
