In recent years, there has been a significant increase in interest in tuning the emission wavelength of InAs quantum dots (QDs) to wavelengths compatible with the already existing silica fiber networks. In this work, we develop and explore compositio

Thermal decomposition of GaAs nanowires is investigated. Radially it is faster for zinc-blende, due to nano-faceted sidewalls. In contrast, wurtzite forms stable single-faceted sidewalls with decomposition only via step-flow from the tip.

InGaAs quantum wells embedded in GaAs nanowires can serve as compact near-infrared emitters for direct integration onto Si complementary metal oxide semiconductor technology. While the core-shell geometry in principle allows for a greater tuning of c

Low-bandgap semiconductor nanowires (NWs) attract considerable interest for mid-infrared (MIR) photonics and optoelectronics, where ideal candidate materials require surface-passivated core–shell systems with large tunability in band offset, lineup

Recent demonstrations of direct integration of GaAs-based nanowire lasers on Si photonic circuits exhibited efficient in-coupling of lasing emission to proximal waveguides - however, transmission in the Si waveguide suffered from high absorption loss

Realizing telecom-band lasing in GaAs-based nanowires (NW) with low bandgap gain media has proven to be notoriously difficult due to the high compressive strain built up in the active regions. Here, we demonstrate an advanced coaxial GaAs-InGaAs mult

Semiconductor nanowire (NW) lasers are attractive as integrated on-chip coherent light sources with strong potential for applications in optical communication and sensing. Realizing lasers from individual bulk-type NWs with emission tunable from the
