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

State bistability between pure- and mixed-mode states in a 1550 nm vertical-cavity surface-emitting laser subject to parallel optical injection

“…emiconductor lasers (SLs) under optical injection have attracted much attention from both fundamental and application viewpoints. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Results demonstrated that significant improvements of lasing characteristics, such as laser spectral narrowing, modulation bandwidth enhancement, and frequency chirp reduction, can be achieved under injection-locking operating conditions. [1][2][3] On the other hand, optical injection can drive a SL into diverse nonlinear dynamical states including period one, period two, quasi-period, and chaos, [8][9][10][11][12][13][14][15][16][17][18][19][20][21] which have potential applications in photonic microwave generation, secure optical communication, fast physical random number (PRN) generation, and chaotic lidar.…”
