The pump-probe measurements of ZnS phosphor samples and a discussion of the temporal walk-off of pulses in the sample are illustrated in the present chapter. I will address the issue of chirp and temporal walk-off of the laser pulses if a white light continuum is used as a probe beam. Various challenges are highlighted for practical photonic switching applications using semiconductor quantum dots.

摘要

The pump-probe measurements of ZnS phosphor samples and a discussion of the temporal walk-off of pulses in the sample are illustrated in the present chapter. I will address the issue of chirp and temporal walk-off of the laser pulses if a white light continuum is used as a probe beam. Various challenges are highlighted for practical photonic switching applications using semiconductor quantum dots. The last part of the chapter is devoted to finding an answer to the question of whether an all-optical switch is better than other switching devices. The concept of optical transistors and the potential for optical logic circuits to revolutionize information processing are also discussed in this section at length.
