The fields of the invention are electronics, oscillating circuits, radio frequency circuits and optoelectronics. The converter comprises an optoelectronic oscillator (OEO), which is the local oscillator (LO) for the frequency conversion operation, and an RF signal injection circuit. The OEO uses a single Mach-Zehnder (MZ) electro-optic modulator and a single photodetector to enable simultaneous up/down frequency conversion of the radio frequency signal from the input of the converter. The frequency conversion is based on the intermodulation that occurs inside the MZ modulator."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Up/down photonic frequency converter for incoming radio frequency (RF) signals built into the optoelectronic oscillator (OEO)","description":"A compact photonic converter for radio frequency (RF) signals comprising fewer components than in the prior art.
