Description
Technical Field
The disclosure relates to the technical field of microwave photonics, in particular to an on-chip integrated double-ring photoelectric oscillator.
Background
The high-purity microwave signal is greatly applied to the military and civil fields, is widely applied to a radar system, a detection system, an electronic countermeasure system and a communication system, and has great research value and application value. Photonics-based methods generate microwaves, which can produce high-purity microwave signals of high frequency and low phase noise. Among them, an Optical Electrical Oscillator (OEO) is widely studied because it can generate a microwave signal and an ultra-low phase noise. The phase noise of a traditional crystal oscillator frequency-doubled microwave signal of 10GHz has-118 dBc/Hz @10kHz, and the phase noise of military-grade OEO can reach-140 dBc/Hz @10 kHz. The reduction of the phase noise of the microwave source has a very positive effect on the whole system.
The traditional double-ring OEO is mainly built by discrete devices, two coils of long single-mode optical fibers are used as double rings in an optical loop part to inhibit the generation of system side modes, and the OEO is kept to be capable of starting oscillation in a single mode. The traditional double-ring OEO signal source adopts a mode of adding modulation to a directly modulated laser and a laser source, an optical coupler also adopts a separate polarization beam splitter and a beam combiner, and the whole link also needs to use a polarization controller to regulate and control the polarization state of light. The whole system is complex and large in volume.
In conclusion, the traditional double-ring OEO has larger volume and is not beneficial to being used in the fields of airborne radar and aviation; because discrete devices are adopted, a plurality of independent power supplies are needed to supply power to the whole system, and the system is greatly complicated; the double ring adopts a long optical fiber as an optical transmission medium, and the temperature sensitivity and the vibration sensitivity of the optical fiber greatly limit the performance of the system in a complex environment.
