Frequency Stabilization of Wideband-Tunable Low-Phase-Noise Optoelectronic Oscillator Based on Fundamental and Subharmonic RF Injection Locking

Frequency Stabilization of Wideband-Tunable Low-Phase-Noise Optoelectronic Oscillator Based on Fundamental and Subharmonic RF Injection Locking

A frequency stabilization scheme for a wideband-tunable optoelectronic oscillator (OEO) based on fundamental and subharmonic RF injection locking is proposed, achieving a tuning range of 2–22 GHz with low phase noise. The injection-locked performance of the OEO using the fundamental RF signal and it...
