High efficiency silicon nanodisk laser based on colloidal CdSe/ZnS QDs

INTRODUCTION: Using colloidal CdSe/ZnS quantum dots in the submicron-sized silicon disk cavity, we have developed a visible wavelength nanodisk laser that operates under extremely low threshold power at room temperature. METHODS: Time-resolved photoluminescence (PL) of QDs; nanodisk by e-beam lithog...

description INTRODUCTION: Using colloidal CdSe/ZnS quantum dots in the submicron-sized silicon disk cavity, we have developed a visible wavelength nanodisk laser that operates under extremely low threshold power at room temperature. METHODS: Time-resolved photoluminescence (PL) of QDs; nanodisk by e-beam lithography. RESULTS: Observation of lasing action at 594 nm wavelength for quantum dots on a nanodisk (750 nm in diameter) cavity and an ultra-low threshold of 2.8 µW. CONCLUSION: From QD concentration dependence studies we achieved nearly sevenfold increase in spontaneous emission (SE) rate. We have achieved high efficient and high SE coupling rate in such a QD nanodisk laser.
