Abstract :
XPM efficiency associated with intersubband transition in InGaAs/AlAsSb quantum well waveguide is enhanced by use of facet reflection. The probe experiences the pump-induced index change twice, thereby increasing the XPM efficiency two times. XPM-based wavelength conversion at 40Gb/s is demonstrated.
