All photonic-gain Optoelectronic Oscillator at 10 GHz

We present a 10 GHz optoelectronic oscillator (OEO) based on optical amplification. The setup uses a 1-km of standard optical fiber at 1.5 $\mu$m and a semiconductor optical amplifier (SOA). The phase noise is -90 dBc/Hz at 100 Hz and 132 dBc/Hz at 10 kHz, currently limited by the oscillator noise floor.
