We present the 1.55μm AlGalnAs/InP microcavity laser based optoelectronic oscillators (OEOs) for narrow-linewidth photonics microwave signal generation. The microwave signals with 3-dB linewidths of about 300 Hz are obtained experimentally by the OEOs.
In the perspective of a monolithic integration of an optoelectronic oscillator on photonic integrated circuits, we evaluate the performances of integrated DFB laser and electro-absorption modulator devices. For this purpose two identical chips have been used, the first for laser emission and amplitude modulation and the second for photo-detection. The link performances have been evaluated for different...
In this paper, the transfer function theory is used to model the phase noise power spectral density in coupled optoelectronic oscillators. A resonator is placed into the model in order to take into account the quality factor (Q) enhancement due to the optical loop. The results of this model are then compared with experimental measurement results. The model is able to describe the phase noise spectrum...
