Excitation power density dependent photoluminescence (PL) measurements of an ensemble of ordered lateral quantum dot (QD) molecules containing on average 4 and 8 QDs are carried out. Asymmetric broadening of the PL spectra is observed with increasing

Picosecond bleaching dynamics of vertically stacked self-assembled quantum dots (QDs) is investigated by means of time-resolved pump-probe differential reflection spectroscopy (TRDR) at room temperature (RT). We observe that the absorption spectrum,

We report all-optical switching due to state-filling in quantum dots (QDs) within a Mach-Zehnder Interferometric (MZI) switch. The MZI was fabricated using InGaAsP/InP waveguides containing a single layer of InAs/InP QDs. A 1530-1570 nm probe beam is
