چکیده :

This paper reports an opto-electro-thermal analysis of VCSEL structures with a surface-relief filter and different aperture diameters. 808-nm GaAs/AlGaAs VCSELs with different aperture diameters and different surface-relief filter diameters are studied and the LI curves, the optical spectra, and the temperature peaks of the devices are obtained. Also, the impact of utilizing different oxide apertures on the temperature peak is shown. The effect of the surface-relief filter diameter on VCSEL's performance is also investigated, aiming to improve single-mode operation while maximizing the output power.
