Photonic switching in InAs/InP quantum dots


We report all-optical switching due to state-filling in quantum dots (QDs). The switching energy is as low as 6 fJ since state-filling requires only 2 electron-hole pairs per QD. The single layer of InAs/InP QDs is inserted within a InGaAsP/InP waveguide which are processed into a Mach-Zehnder interferometric switch (MZI). A 1530-1570 nm probe beam is… (More)
