Integrated Duo Wavelength VCSEL Using an Electrically Pumped GaInAs/AlGaAs 980 nm Cavity at the Bottom and an Optically Pumped GaInAs/AlGaInAs 1550 nm Cavity on the Top

Figure 10

Plot of reflectivity versus wavelength for the top DBR mirror system of the designed top 1550 nm VCSEL section. 24 pairs of GaAs/Al0.8Ga0.2As gave 0.994 reflectivity.
