A Study on Modulation Configuration of Optoelectronic Oscillators Using Direct Modulation of Semiconductor Lasers

초록

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.
