Hybrid opto-electronic oscillator for single-sideband microwave photonics

A single-sideband opto-RF oscillator based on a monolithic InGaAsP chip containing two distributed feedback (DFB) lasers is demonstrated. The heterodyne signal is stabilised by a hybrid method, combining optical and electronic feedback. It leads to a locking of the beating frequency onto a filtered...

Zusammenfassung:A single-sideband opto-RF oscillator based on a monolithic InGaAsP chip containing two distributed feedback (DFB) lasers is demonstrated. The heterodyne signal is stabilised by a hybrid method, combining optical and electronic feedback. It leads to a locking of the beating frequency onto a filtered version of itself. The table-top setup provides a phase noise level down to −75 dBc/Hz at 1 kHz offset from a 10 GHz carrier. Potential phase noise improvement and integration scheme in a single component are discussed.
