Injection-Locked Hybrid Optoelectronic Oscillators for Single-Mode Oscillation

Abstract

We demonstrate single-mode extraction from multiple modes in a 30-GHz optoelectronic oscillator (OEO) by injecting OEO modes into an electrical oscillator. The electrical oscillator is injection-locked by one OEO mode resulting in single-mode oscillation. The single-mode oscillation frequency can be tuned by changing the electrical oscillation frequency.
