Optical response of quantum dot multilayer structures

Saturated Gain of Doped Multilayer Quantum Dot Semiconductor Optical Amplifiers

The effect of the number of quantum dot (QD) layers on the saturated gain of doped QD semiconductor optical amplifiers (SOAs) has been studied using multi-population coupled rate equations. The developed model takes into account the effect of carrier coupling between adjacent layers. It has been found that increasing the number of QD layers (K) increases the unsaturated optical gain for K<8 and...

Photosensitive quantum dot composites and their applications in optical structures

Commercially available CdSe/ZnS and PbSe colloidal semiconductor quantum dots were employed to produce both an electron beam sensitive poly methyl methacrylate PMMA -quantum-dot QD positive composite via a prepolymerization processing and an electron beam and ultraviolet UV light sensitive SU-8-QD negative composite via a direct dispersion procedure. Compared to the QDs in the original colloida...
