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

Synchronization of unidirectionally coupled multi-transverse-mode vertical-cavity surface-emitting lasers

The synchronization of unidirectionally coupled multi-transverse-mode vertical-cavity surface-emitting lasers (VCSELs) is numerically studied. It is demonstrated that synchronization can be achieved between each transverse mode of a master laser and its counterpart, a slave laser. This result opens the opportunity for multichannel chaotic communications by use of multi-transverse-mode VCSELs. I...

Polarization switching control in vertical-cavity surface-emitting lasers

Orthogonal polarizations within vertical-cavity surface-emitting lasers ~VCSEL! lase at slightly different wavelengths. We describe the use of optical feedback to confine polarization variations to reproducible injection currents. An external cavity is used to select specific wavelengths that reflect back into the VCSEL, hence, changing the cavity Q for the different polarization states. With t...
