Millimeter wave generation and modulation system and method of millimeter wave optical fiber optical fiber transmission system

The invention discloses a millimeter wave generating and modulating system and method of millimeter wave optical fiber transmitting system, which is characterized by the following: dividing single-frequency laser into two paths through central station; proceeding phase modulation for one-path wave through low-frequency periodical microwave signal without any disposing for the other signal; overlapping and interfering two-path optical wave; transmitting the wave to base station through optical fiber to generate optical current detected by optical detector; making the current signal contains each harmonic wave in the current signal; fetching the high-harmonic wave through band pass filter as needed millimeter wave signal; realizing the optical generation of millimeter wave; modulating the optical strength of overlapped and interfered wave not to generate millimeter wave signal; obtaining the millimeter wave of modulated information; realizing the modulating transmission of information from central station to ba
