“…When the injection power is linearly increased or reduced, the threshold varies, and it is dependent on the optical injection frequency. A similar phenomenon can also be observed in Fabry-Pérot laser diodes [18].…”

We report a novel optical pulse generation method for high-speed wavelength switching of amplified nanosecond (ns) laser pulses resonant to atomic transitions. Under free-running conditions, a slave laser diode is blue-detuned with tens of GHz relative to the master laser. A nanosecond pulse chain generated by modulating the continuous-wave master laser with a fiber-pigtailed electro-optical intensity modulator is injected into the slave laser diode to fast switch the slave laser's wavelength back and forth. The output beam of the slave laser is filtered by a temperature-controlled etalon to get the amplified pulse chain. Based on our dynamic injection locking scheme, we produce an ns-scale square pulse chain with an effective ON/OFF ratio ∼10⁸, considering at least the 60 dB scattering suppression by tuning the light-atom interactions with far off-resonance detuning and the 26.7 dB suppression ratio of the etalon. By studying the dynamic processes of injection locking, we determine the dependence of injection locking on both the injection power and the frequency detuning.

“…The bistability hystereses corresponding to dominant modes are clearly visible, while the hysteresis corresponding to the side mode is somewhat degraded, which might be the consequence of the SL's sensitivity on current intensity and temperature fluctuations [29]. Although this work focuses on the demonstration of the bistability effect in sophisticated laser design, it does not provide an insight into the mechanism of wavelength switching, nor estimate of the switching time between the hysteresis branches.…”

“…A recent experimental study of the dual mode FP-LD, based on the built-in external cavity [29], has demonstrated that the bistability of the two dominant modes can be achieved by injecting the light from the ML into one of the suppressed side modes situated between the two dominant modes, and further controlled by the wavelength detuning from this side mode. The bistability hystereses corresponding to dominant modes are clearly visible, while the hysteresis corresponding to the side mode is somewhat degraded, which might be the consequence of the SL's sensitivity on current intensity and temperature fluctuations [29].…”

Theoretical study of switching of a bistable injectionlocked Fabry-Pérot laser by frequency detuning variation is performed and presented. It has been found that the shortest switching time of the master laser, which allows for the slave laser to be successfully switched by frequency detuning variation, reaches the values of several picoseconds, and up to 200 ps. The disproportion of the slave laser switching times with respect to the switching direction is found (3 versus 0.3 ns), and techniques for its equalization, as well as for minimization of the slave laser total switching time, are presented and discussed. We found that the modest increase of the master laser switching time establishes the balance between the two directions of the slave laser switching, providing almost one order of magnitude improvement in comparison to the results achieved for the shortest possible master laser switching times.

“…However, the coherency of these lasers is a vital issue to obtain a reduced phase noise of the system. Subsequently, various existing approaches to further improve the performance of these configurations have been reported; for instance, external optical injection [11], side mode injection [12], self-injection [13], etc.…”

We implemented a tunable dual-longitudinal-mode spacing InGaN/GaN green (521-528 nm) laser diode by employing a self-injection locking scheme that is based on an external cavity configuration and utilizing either a high or partial-reflecting mirror. A tunable longitudinal-mode spacing of 0.20 -5.96 nm was accomplished, corresponding to a calculated frequency difference of 0.22-6.51 THz, as a result. The influence of operating current and temperature on the system performance was also investigated with a measured maximum side-mode-suppression ratio of 30.4 dB and minimum dual-mode peak optical power ratio of 0.03 dB. To shed light on the operation of the dual-wavelength device arising from the tunable longitudinal-mode spacing mechanism, the underlying physics is qualitatively described. To the best of our knowledge, this tunable longitudinal-mode-spacing dual-wavelength device is novel, and has potential applications as an alternative means in millimeter wave and THz generation, thus possibly addressing the terahertz technology gap. The dual-wavelength operation is also attractive for high-resolution imaging and broadband wireless communication.
