Abstract

The invention proposes a low-noise photon microwave source device adopting a long wavelength vertical cavity laser. The device comprises an external light injection module and a double-cavity feedback module, wherein the external light injection module comprises an adjustable laser source, a convex lens, a half transparent and half reflecting mirror, an optical power meter, a first polarization controller, an opto-isolator and a 1550 nm-vertical cavity semiconductor laser; the double cavity feedback module comprises a half transparent and half reflecting mirror, a third reflecting mirror, a fourth reflecting mirror, a second polarization controller, a third polarization controller and a variable attenuator used for reducing optical power to an appropriate value.

Description

technical field [0001] The invention relates to the field of information technology, in particular to an all-optical photon microwave signal device based on external light injection and double-cavity feedback long-wavelength vertical cavity semiconductor lasers. Background technique [0002] Microwave generation technology is widely used in modern communication, military, radar and other fields. In recent years, photonic microwave technology has attracted attention as an emerging technology for generating microwave signals. It has attractive application prospects in the fields of Radio-over-Fiber (ROF), mobile phone 4G, and 5G technologies. . [0003] The existing photonic microwave generation methods can basically be divided into three categories: pure electronic, photoelectric hybrid and all-optical methods. For pure electronic methods, crystal oscillation can be used to generate seed microwaves, and then high-frequency signals can be obtained through resonance, but such ...
