“…Besides a reduced footprint, the interest of taking the minimal length for the external cavity is to remain in the corresponding short cavity regime. 15 Indeed, in this case, the laser is known for being more robust against feedback perturbation which would be detrimental here. In our integrated demonstrator, the external cavity has a total length of 2.8 mm.…”

In this conference proceeding, we present a novel technique to control the emission of dual-wavelength lasers. Using a well designed external cavity, we demonstrate that tuning the optical feedback phase allows to efficiently tailor the output power balance between the two wavelengths emitted by the laser. With this technique, a complete switch between one and the other mode can also be achieved and we report a suppression ratio up to 40 dB. Due to its simplicity, the structure can be monolithically integrated easily with the laser itself and offers a precise control of the dual-wavelength emission using a single control parameter.

“…The corresponding output of ECF-SL behaves a sudden power dropout and then recoveries gradually with a frequency of ~MHz, which is much lower than the relaxation oscillation frequency [18] and the physical mechanism is considered as the unstable saddle-node and intermittent instability involved in ECF-SLs [19]. Different from LFFs, some intermittent phenomena have also been observed and studied in a short (~10 -3 m) external cavity SL [20][21][22]. Bosco et al experimentally investigated the nonlinear dynamics of a photonic integrated circuit consisting of a SL with short ECF [20] and found a crisis-induced intermittent route to chaos [21].…”

The physical mechanism is explained as the intermittently switching between separated attractors from different external-cavity modes in phase space and the stochastic switching time was then utilized for random number generation [22].…”

“…On the one hand, the success of the former opens important opportunities for the field of laser dynamics as its successful development creates a fruitful and suitable context for harnessing the targeted behaviour and applications [7,9,13]. On the other hand, the latter makes it finally possible to overcome notorious stability issues and to drastically increase the complexity of a system without unreasonably increasing its cost and bulkiness [6,[14][15][16]. Simultaneously, generic foundry platforms and multi-project wafer runs also offer the exciting chance to make custom lasers and systems without the need to master all the steps of photonic integrated circuit growth [6,17,18].…”

The idea of using the dynamical behaviour of a semiconductor laser to perform a certain processing operation of an input signal has been around for quite a long time. While the unidirectional optical injection scheme seems well suited to such a target-with the injection serving as an optical carrier for the input signal-the impact of a modulation of the injection beam still requires thorough investigation. Here, we study the case of an optically injected laser with a simple single-tone modulation term added to the injection signal. We analyse the impact of amplitude modulation on the laser dynamics, and particularly focus on the evolution within the injection locking range. We highlight clear passband behaviour corresponding to the laser resonance at its relaxation oscillation frequency, and characterize its features for various parameter changes. Next, we report dramatic differences between amplitude and phase modulation as the latter quickly leads to a loss of the injection locking and to the emergence of chaotic dynamics in place from the passband response identified in the case of amplitude modulation. At last, we discuss the suitability of using laser diodes for signal filtering, as was recently proposed by others, and identify the main remaining issues that need to be overcome.
