Optical Gain of Vertically Coupled Cd<sub>0.6</sub>Zn<sub>0.4</sub>Te/ZnTe Quantum Dots

Optical Gain of Vertically Coupled Cd<sub>0.6</sub>Zn<sub>0.4</sub>Te/ZnTe Quantum Dots

The optical modal gain of Cd<sub>0.6</sub>Zn<sub>0.4</sub>Te/ZnTe double quantum dots was measured using a variable stripe length method, where large and small quantum dots are separated with a ZnTe layer. With a large (~18 nm) separation layer thickness of ZnTe, two gain spe...
