Abstract
We demonstrate high temperature operation of InAs quantum dot lasers through active region engineering. We grew an n-doped region within the InAs quantum dot (QD) layer and incorporated a 10 nm p-GaAs modulation-doped layer within a 43 nm GaAs spacer layer, both of which are essential components of the active region of the InAs QD laser device. The co-doping scheme enables the demonstration of InAs QD laser device with only seven layers of InAs QDs in the active region for high temperature operation, which is compared with a conventional undoped InAs QD laser device. A Fabry-Pérot laser device with as-cleaved facets and a co-doped InAs QD active region enables ultra-high temperature pulsed-biased O-band laser operation up to 202 °C, compared to 180 °C for conventional undoped InAs QD laser, and without requiring high-reflective facet coatings.
