Abstract

Efficient near-infrared (NIR) light sources are essential for a wide range of applications such as telecommunications, optoelectronic devices, biomedical sciences, infrared imaging, and machine vision. Colloidal quantum dots (QDs) have emerged as a promising platform for NIR technologies due to their tunable optical properties across the NIR spectrum, compatibility with silicon-based technology infrastructure, and ease of large-scale integration into nanophotonic systems. Coupling colloidal QDs with plasmonic structures provides an enhanced control over their optical properties. In this work, we investigate the coupling of a gold plasmonic crescent metasurface with NIR-emitting colloidal PbS/CdS QDs, at the telecommunication wavelength of 1.55 μm. The metasurface was specifically designed to allow for the selective excitation photoluminescence (PL) enhancement with polarization control, capitalizing on the anisotropic nature of the plasmonic crescents. Maximum PL enhancement factors of 1.6 were observed, with a strong dependence on the excitation wavelength and polarization. These findings, supported by full-wave three-dimensional finite-difference-time-domain (FDTD) numerical simulations, offer strategies to control and optimize the performance of colloidal QD-based NIR light sources for a wide range of applications.
