Time-Delay Signature Suppression of Polarization-Resolved Chaos Outputs from Two Mutually Coupled VCSELs

IEEE Photonics Journal, 2013
Time-delay (TD) signature performances of polarization-resolved chaos outputs from two mutually coupled vertical-cavity surface-emitting lasers (MC VCSELs) are investigated through detailed simulations by means of self-correlation function (SF) and ...

Long-wavelength VCSELs for sensing applications

, 2012
Long-wavelength VCSELs with emission wavelengths beyond 1.3 μm have seen a remarkable progress over the last decade. This success has been accomplished by using highly advanced device concepts which effectively overcome the fundamental technological ...

Polarization properties and instabilities of QD VCSELs

, 2010
International audienceQuantum well (QW) VCSELs have a tendency to switch their polarization from one linearly polarized (LP) mode to the orthogonal one when changing the operation conditions.

Chaotic polarization dynamics and chaos synchronization in VCSELs

, 2009
International audienceWe review our recent results related to nonlinear polarization dynamics and chaos in VCSELs. The possibility to generate multimode chaos motivates the study of chaos synchronization in coupled VCSELs and its application for secure ...

Reconfigurable Millimeter-Wave Generation via Mutually Injected Spin-VCSELs

Photonics
We propose a novel scheme for generating high-frequency millimeter-wave signals by exploiting period-one (P1) dynamics in a mutual injection configuration of two spin-polarized vertical-cavity surface-emitting lasers (spin-VCSELs).

Cavity structures for low loss oxide-confined VCSELs [PDF]

, 1997
The authors examine the threshold characteristics of selectively oxidized VCSELs as a function of the number, thickness, and placement of the buried oxide apertures. The threshold current density for small area VCSELs is shown to increase with the number

Performance of VCSELs for SCT links

, 1998
Vertical Cavity Surface Emitting Laser (VCSEL) diodes will be used as the light source for SCT optical links. In this note we report about measurements of electrical and optical properties of VCSELs relevant for the design of new version of driving and ...
