Highly Spectrally Pure 90-GHz Signal Synthesis Using a Coupled Optoelectronic Oscillator

Chromatic Dispersion measurement of short optical fibers by sinusoidal phase modulation of a monochromatic light

“…With the approach in Fig. 5 we have demonstrated recently a 90 GHz signal generator (harmonic mixing from a 30 GHz COEO) with an ultra-low phase noise level of -104 dBc/Hz at 1 kHz offset frequency [7]. The results are displayed on Fig.…”

Effects of Polarization Mode Dispersion on an All Polarization Maintaining Fibers Based Coupled Optoelectronic Oscillator

“…Fig. 1 It is the same as the one used in [3] where the optical delay line LO is made of 400 m SMF and more details about the other components can be found is this reference. The optimization consists simply in replacing the polarization controller and the optical delay line by a 400 m PMF fiber spool and see how the COEO performs.…”

“…The coupled optoelectronic oscillator (COEO) is among these solutions. As to mention, it has allowed the generation of electrical signals at 10 GHz, 30 GHz and 90 GHz with phase noise levels at 1 kHz offset frequency as low as -120 dBc/Hz, -114.4 dBc/Hz and -104 dBc/Hz respectively [2,3]. A typical architecture of a COEO is shown in Fig.…”

Uncertainty Evaluation on a 10.52 GHz (5 dBm) Optoelectronic Oscillator Phase Noise Performance

“…Hao et al proposed a topology to break the limitation of mode building time in an OEO [ 4 ]. Ly et al introduced coupled OEOs delivering a 90 GHz signal [ 5 ]. Integrated microwave optoelectronic oscillators were created by Tang et al [ 6 ].…”
