Paper Abstract

The first investigation of the effect of mesa plated sidewall heatsinks on the performance of red oxide-confined verticalcavity surface-emitting lasers (VCSELs) is reported. Single mode (SMSR>20dB) visible (670 nm) VCSELs were fabricated with an AlGaInP active region and AlGaAs distributed Bragg reflectors (DBRs). Copper is electroplated on and around VCSELs with different mesa diameters with a variety of overlap sizes. A trend of reduction in thermal impedance for some devices has also been observed with increasing the plating overlap size.
