“…With this scheme, referred to as selective orthogonal feedback, it has been observed that the feedback linearly shifts the laser emission frequency [15,16] and, under strong feedback, polarization SWs have also been observed [17,18]. Simulations based on the spin-flip model for vertical-cavity surface-emitting lasers (VCSELs) [17] and on a two-mode model for edge-emitting lasers (EELs) [18] showed a good agreement with the observations.…”

“…Several experiments have been performed in which only one polarization, the natural lasing one, is selected and fed back into the orthogonal one [15][16][17][18]. With this scheme, referred to as selective orthogonal feedback, it has been observed that the feedback linearly shifts the laser emission frequency [15,16] and, under strong feedback, polarization SWs have also been observed [17,18].…”

We study experimentally the dynamics of vertical-cavity surface-emitting lasers (VCSELs) with polarizationrotated (PR) optical feedback, such that the natural lasing polarization of a VCSEL is rotated by 90 deg and then is reinjected into the laser. We observe noisy, square-wave-like polarization switchings with periodicity slightly longer than twice the delay time, which degrade to (or alternate with) bursts of irregular oscillations. We present results of simulations that are in good agreement with the observations. The simulations demonstrate that close to threshold the regular switching is very sensitive to noise, while well above threshold is less affected by the noise strength. The frequency splitting between the two polarizations plays a key role in the switching regularity, and we identify wide parameter regions where deterministic and robust switching can be observed.

“…Optical bistability (OB) is an optical nonlinear phenomenon in which the system exhibits two output powers for the same input power, and it has many potential applications such as optical communication, optical switch, optical memory, and optical logic. Since it was first reported in a passive sodium vapor medium by Gibbs et al in 1976 [1], OB has been extensively studied in both experiment and theory for several decades [2][3][4][5][6][7][8][9][10]. Active OB of lasers has also been predicted and experimentally realized with a absorptive medium or a nonlinear dispersive medium in laser resonators [11,12].…”

We report on the experimental demonstration of stable all-optical switching between two steady state values of optical bistability from a laser diode end-pumped quasi-three-level Tm,Ho:LLF laser in the 2 µm spectral region. The width of the hysteresis cycle and jump power values can be efficiently controlled by changing the length of the cavity, which is very important to adjust and optimize the optical switching process. The all-optical bistable switching effect is realized by only adding short positive and negative trigger pulses to the pump light. This is, to our knowledge, the first observation of all-optical bistable switching in a rare earth doped solid state laser.

“…Orthogonal optical feedback has been used in semiconductor lasers either to improve frequency stability and spectral characteristics [3], [4], or to induce instabilities and dynamical behavior [1], [5], [6], and some other applications [7], [8], [9], [10]. Since the first report by Kawaguchi in 1988 [3], some of these applications take advantage of the emission frequency dependence on the orthogonal feedback power.…”

Abstract-We report experimental and numerical investigations concerning semiconductor lasers emission under polarization-rotated feedback. We experimentally observe that for some semiconductor lasers the weak TM mode does lase even in the absence of TM feedback and we monitor how the TE and TM emissions evolve with the increase of the TM feedback strength. The emission frequency of a semiconductor laser subject to polarization-rotated feedback experiences a shift proportional to the optical power fed back into the laser [1]. We aim to investigate what affects the sensibility of the frequency of semiconductor lasers to polarization-rotated feedback. Experimentally, we measured the proportionality coefficient β between frequency shift and feedback power for different lasers and characterized how it varies with some parameters. Theoretically, we made numerical calculations using a rate equation model [2], and our results show a critical dependence of the β coefficient on the gain self-and cross-saturation of both modes and the relations between these saturation coefficients.
