The invention discloses a photon-assisted millimeter wave and laser hybrid communication transmitter, which belongs to the technical field of microwave photonics, and is characterized in that two beams of frequency coherent light are generated by using an optical frequency comb, one beam of optical beam is divided into two beams of light through a first polarization-maintaining optical coupler after a modulated optical signal is obtained through a light intensity modulator, and the modulated optical signal is transmitted to a second polarization-maintaining optical coupler; one path of modulated optical signals shunted by the first polarization-maintaining optical coupler passes through an optical amplifier and is sent to a laser antenna for radiation output through an optical fiber, and the other path of modulated optical signals is combined with unmodulated optical signals generated by an optical frequency comb at a second polarization-maintaining coupler; and a millimeter wave radio frequency signal is generated through optical heterodyne of the photoelectric detector and is radiated and output through the millimeter wave antenna. An optical frequency comb is used for generating a multi-carrier light beam, one path serves as a laser signal, the other path generates a millimeter wave radio frequency signal through optical heterodyne, emission of the laser signal and the millimeter wave signal is achieved through a laser antenna and a millimeter wave antenna which are integrated through a common aperture, and the millimeter wave and laser hybrid communication function is achieved through one system.
Description
technical field [0001] The invention belongs to the technical field of microwave photonics, and more particularly, relates to a photon-assisted millimeter-wave and laser hybrid communication transmitter. Background technique [0002] With the gradual exhaustion of spectrum resources in the microwave frequency band, the development of communication frequencies to higher frequency bands has been promoted. Millimeter-wave frequency bands and lasers have broadband spectrum resources ranging from several GHz to tens of GHz, which is an important development direction for future wireless communications. Millimeter-wave communication and laser communication have rich bandwidth resources, large communication capacity, narrow emission beams, and higher security, beyond the existing interference frequency range, and strong anti-electromagnetic interference. The advantages of wide frequency band, high reliability and high security of millimeter wave communication and laser communicatio...
