Instabilities in quantum dot semiconductor lasers at 1.3 μm

Not Accessible

Your library or personal account may give you access


InAs/GaAs Quantum Dot (QD) semiconductor lasers emitting near 1300 nm present many interesting features for non-linear dynamics as they combine a relatively low line-width enhancement factor with strong damping of the relaxation oscillations. As a result these devices remain stable under large levels of optical feedback but can display instabilities at high temperature where the line-width enhancement factor increases significantly. Here we show that these devices also display very interesting features under the influence of optical injection from a narrow line-width master laser.
