Abstract :
A compact variable all-optical buffer using semiconductor quantum dot structures is proposed. The buffering effect is achieved by slowing down the optical signal using an external control light source to vary the dispersion characteristic of the medium. The theoretical model shows that a slow-down factor of more than 104 with negligible group velocity dispersion is achievable.
