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

<div>Plot of reflectivity versus wavelength for the bottom DBR mirror system of the designed bottom 980 nm VCSEL. Here, 24 pairs of GaAs/Al<sub>0.8 </sub>Ga<sub>0.2 </sub>As gave 0.994 reflectivity.</div>
