Two SOA-based coupled optoelectronic oscillators (COEO) at 30 GHz and 10 GHz have been studied. These systems have been designed thanks to a preliminary study of the noise of various optical amplifiers (SOA and EDFA). The COEOs measured single sideband phase noise level is −132 dBc/Hz and −125 dBc/Hz at 10 kHz offset from 10 GHz and 30 GHz respectively. The architecture proposed enabled a rejection of spurious modes above 70 dB.
