Abstract :
Ultrafast all-optical cross-phase modulation in InGaAs/AlAsSb quantum wells, where interband dispersion is modulated by intersubband excitation, is applied to a MZI switch, demonstrating all-optical signal processing such as demultiplexing and wavelength conversion of 160-Gb/s OTDM signal.
