“…Finally, the improved theoretical understanding provided by the present work will assist the design of novel opto-electronic oscillator schemes. Indeed, in an alternative architecture it is possible to remove the electronic synthesizer, and use the beatnote signal received by the photodiode to drive the MZM, thus obtaining a selfreferenced hybrid opto-electronic oscillator with singlesideband output [34,35]. Also, it has started being used on integrated single components [36].…”

The phase synchronization of two semiconductor DFB lasers submitted to both frequencyshifted cross-injection and self-feedback is investigated, both numerically and experimentally. A dedicated setup based on monolithic DFB lasers permits to effectively lock the frequency difference of the two lasers on an external reference over a broad range of parameters. In agreement with a delayed rate equation model, it is shown that the sensitivity of the locking to the optical feedback phases is mitigated by using strong cross-injection, thus paving the way to applications for microwave photonics.Other synchronization dynamics can also be observed, such as bounded-phase oscillations.

“…Many subsequent studies on semiconductor lasers with optoelectronic feedback were indeed focused on dynamical instabilities [2]. More recently, some authors proposed setups based on various combinations of optoelectronic feedback and optical injection [5] or feedback [6], [7] with the aim of generating stable and possibly tunable microwave signals. Direct current modulation of a microsquare laser was used in [8] to generate tunable signals with good phase noise.…”

A direct-modulation OEO (DM-OEO) generating stable 10 GHz and 20 GHz signals is presented. A single loop and a dual loop approach are implemented and compared. We show an output signal of 15 dBm RF power, and a phase noise as low as -135 dBc/Hz at 10 kHz offset from the 10 GHz carrier. The 20 GHz second harmonic exhibits a noise level of -127 dBc/Hz at 10 kHz. A high spur level reduction is also obtained in the dual loop architecture.

“…This has been obtained by (i) the introduction of a RF interferometer thanks to the use of two delay lines, and (ii) a significant shortening of the optical feedback loop (see Fig. 1(a)) [3]. The RF interferometer leads to suppression, by destructive interference, of the spurs that are due to the fiber loops before the photodiodes.…”
