This paper investigates the impact of dislocation density and active layer structure on the degradation mechanisms of 1.3 $\mu \text{m}$ InAs Quantum Dot (QD) lasers for silicon photonics. We analyzed the optical behavior of two sets of samples, havi

$p$ -type modulation doping of the quantum dot active region is known to improve high temperature and dynamic performance of quantum dot lasers. These improvements are critical to realizing commercially relevant quantum dot devices on silicon and are

We analyze the structure of dislocations in electrically aged InAs quantum dot (QD) lasers on silicon to understand gradual device degradation. We find that misfit dislocations lengthen due to carrier injection, experiencing a combination of recombin

The centrifugation method was proposed to extract Au nanocages (AuNCs) from a mixture of the bimetallic Au and Ag alloyed nanocages, Ag and Au core–shell structure, and Au-pitted silver nanocubes. The DDA simulation was found to be a powerful tool
