Polarization switching and hysteresis in vertical-cavity surface-emitting lasers subject to orthogonal optical injection
(Institute Of Electrical And Electronics Engineers, 2014)
We study polarization switching and hysteresis in a vertical-cavity surface-emitting laser (VCSEL) subject to an orthogonal optical injection, such that the polarization of the injected light is perpendicular to that of ...
Dynamics of Normal and Reverse Polarization Switching in 1550-nm VCSELs Under Single and Double Optical Injection
(Institute Of Electrical And Electronics Engineers, 2015-12)
Polarization switching (PS) in 1550nm-VCSELs under single and double pulsed polarized optical injection is investigated experimentally and in theory. ‘Normal’ and ‘reverse’ PS were achieved, respectively, when the device ...
Influence of the injection current sweep rate on the polarization switching of vertical-cavity surface-emitting lasers
(American Institute of Physics, 2006-12)
We study the polarization switching of vertical-cavity surface-emitting lasers based on simulations of the spin-flip model. We show that the switching point depends on the ramp signal used to scan the injected current. ...
Optical router for optical fiber sensor networks based on a liquid crystal cell
(09/04/2003)
Optical fiber sensor networks are evolving rapidly. They are used because of the inert nature of optical fibers allowing no electromagnetic interference and safe applications in inflammable atmospheres; other relevant ...
The use of pulsed electric acoustic technique for measuring electric field profiles in ferroelectric ceramic
(2002-12-01)
The pulsed electric acoustic technique, PEA, have been usually applied to probe space charge profiles in polymers. In this work we show preliminary results obtained with lead zirconate-titanate and niobium, PZTN, ferroelectric ...

All-optical stochastic logic gate based on a VCSEL with tunable optical injection
(IEEE-Inst Electrical Electronics Engineers Inc, 2013-10)
We study the dynamics of a vertical-cavity surface-emitting laser (VCSEL) with continuous-wave (cw) orthogonal optical injection from a tunable laser. We use the dynamical properties of polarization bistability and the ...
Polarization instability, steering, and switching of discrete vector solitons

The use of pulsed electric acoustic technique for measuring the polarization reversal in ferroelectric ceramic samples
(2002-01-01)
The pulsed electric acoustic technique, PEA, has been usually applied to probe space charge profiles in polymers. Preliminary PEA results using a ferroelectric ceramic are presented. If the reverse applied electric field ...
