Abstract :
Sub-picosecond all-optical switching at telecommunication wavelengths has been demonstrated by utilizing an intersubband transition of II-VI-based MQW fabricated in high-mesa waveguide devices with separate confinement heterostructure, where (CdS/ZnSe)/BeMgTe QW is employed as active layer.
