Metasurfaces have recently realised many revolutionary applications such as metalenses, equation solvers, beam shapers, and holographic projection.1–4 However, the conventional metasurfaces are monotask due to their fixed dimensions. Therefore, rea

Flexible, substrate-free nanowire (NW) devices are desirable to overcome the extremely challenging task of integrating III-V or III-N semiconductor devices such as LEDs and lasers on a range of optoelectronic circuits or biochips. In this work, we re

We present single-mode nanowire (NW) lasers with ultralow threshold in the near-infrared spectral range. To ensure the single-mode operation, the NW diameter and length are reduced specifically to minimize the longitudinal and transverse modes of the
