概要
- 論文の詳細を見る
Optoelectronic oscillators (OEOs) are demonstrated using optical single sideband (SSB) which is generated by resonance effect in directly-modulated semiconductor lasers under optical injection. The resonant amplification of modulated optical sideband enhances the optical link efficiency in a target oscillation frequency so that RF threshold gain of OEO can be significantly reduced. The OEOs based on two different modulation configurations --- master laser and slave laser modulation --- show comparable efficiency and phase noise performance.
