Injection locking suppression of coherence collapse in a diode laser with optical feedback

Experimental investigations on nonlinear dynamics of a semiconductor laser subject to optical injection and fiber Bragg grating feedback

“…Diverse external disturbances such as optical injection, optical feedback, optoelectronic feedback, and current modulation have been introduced into semiconductor lasers (SLs), and their influences on the nonlinear dynamics of SLs have been widely investigated [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. Among these external disturbances, optical injection and optical feedback are two commonly adopted schemes.…”

“…Among these external disturbances, optical injection and optical feedback are two commonly adopted schemes. With optical injection, locking and unlocking phenomena in SLs have been extensively studied [6][7][8][9][10]. Under the case of injection locking, optical injection is a useful tool for controlling and stabilizing laser oscillation, and enhancing the modulation bandwidth [6,7].…”

“…With optical injection, locking and unlocking phenomena in SLs have been extensively studied [6][7][8][9][10]. Under the case of injection locking, optical injection is a useful tool for controlling and stabilizing laser oscillation, and enhancing the modulation bandwidth [6,7]. Under the case of unlocking, optical injection drives SL into unlocking dynamical states such as four-wave mixing, period one oscillation (P1), period two oscillation (P2), and chaos oscillation (CO) [8][9][10][11].…”

“…In some applications requiring broad bandwidth chaos signals, optical injection is adopted to enhance the bandwidth of the chaos generated by a SL with optical feedback [21][22][23]. Additionally, in order to suppress the unwanted dynamics induced by optical feedback which is inevitable in practice when SLs are coupled to other optical devices, optical injection is also required to lock the SLs into injectionlocking state [6]. Therefore, it would be valuable to understand the dynamics of SLs subject to both optical injection and optical feedback.…”

Static and dynamic behaviors of vertical-cavity surface-emitting lasers subject to mode-selective feedback

“…The characteristics of semiconductor lasers (SLs) with external optical feedback have attracted considerable interest in past two decades since it is an excellent model for nonlinear optical systems and includes a rich variety of nonlinear dynamics [1][2][3][4][5][6]. In practical optical experiments or optical communication systems, part of the light emitted by the laser always is reinjected due to the reflections of the external mirror, such as fibers, lenses, filters, etc.…”
