Polarization dynamics of a multimode vertical-cavity surface-emitting laser subject to orthogonal optical injection

Polarization synchronization in unidirectionally coupled vertical-cavity surface-emitting lasers with orthogonal optical injection.

We analyze theoretically the polarization dynamics in unidirectionally coupled vertical-cavity surface-emitting lasers (VCSELs). The master VCSEL is subject to an isotropic optical feedback. The slave VCSEL is subject to an orthogonal optical injection from the master VCSEL, i.e., only the linearly polarized mode orthogonal to the dominant linearly polarized mode of the free-running slave VCSEL...

Polarization Properties of Vertical-cavity Surface-emitting Lasers Subject to Variable Optical Feedback Polarization Angle

In this paper, the influence of variable polarization angle (θp) of optical feedback (OF) on the polarization properties of a vertical-cavity surface-emitting lasers (VCSELs) is investigated experimentally. Parallel polarization optical feedback (PPOF) and orthogonal polarization optical feedback (OPOF) are employed, where the polarization light is re-injected back into the laser. For the PPOF ...

Two-frequency injection on a multimode vertical-cavity surface-emitting laser.

We have studied experimentally effects of two-frequency optical injection on a multimode vertical-cavity surface-emitting laser (VCSEL). The injected signal comes from another VCSEL. Polarization switching (PS) with and without frequency locking occurs for relatively small frequency detuning. Outside the regime of polarization switching, the VCSEL demonstrates two types of instabilities. The in...

Optical Injection Locking of Vertical Cavity Surface Emitting Lasers by

Polarization properties of vertical-cavity surface-emitting lasers subject to feedback with variably rotated polarization angle.

Influences of variable-angle polarization-rotated optical feedback on polarization properties of vertical-cavity surface-emitting lasers (VCSELs) are investigated numerically. For the so-called case A (x polarization) feedback, only the x mode is selected to pass through the feedback loop. As the polarization angle is varied from 0 degrees to 90 degrees, the dominant polarization mode switching...
