InAs/InP(100) quantum dot laser with high wavelength stability

Introduction: The lasing wavelength of a semiconductor laser inevitably changes with varying the operation temperature, which is, however, not desirable for applications requiring specific and stable light wavelength. Thus, laser diodes with wavelength insensitive to temperature are fascinating and can drastically ease the critical requirements on precise temperature control. The quantum dot (Q...

Silver-enhanced fluorescence emission of single quantum dot nanocomposites.

A novel plasmon-coupled quantum dot (QD) nanocomposite via covalently interfacing the QD surfaces with silver nanoparticles was developed with greatly reduced blinking and enhanced emission fluorescence.
