Brief
This article proposes and analyzes a novel dual-loop optoelectronic oscillator (OEO) based on all-optical signal processing, utilizing an EDFA for amplification and an FBG for filtering, which achieves low phase noise and high side-mode suppression ratio without electronic components.
Summary
This article proposes and analyzes a novel dual-loop optoelectronic oscillator (OEO) that uses all-optical signal processing by incorporating an erbium-doped fiber amplifier (EDFA) for amplification and a fiber Bragg grating (FBG) for filtering in the optical domain. This design improves the OEO's performance, achieving low phase noise (lower than –120 dBc/Hz at 10 kHz offset) and a high side-mode suppression ratio (SMSR) without relying on electronic filters or amplifiers. The theoretical analysis and simulations demonstrate the potential of this approach for generating high-quality microwave signals.
