NettetHere, we present a review of the status and perspectives of semiconductor nanowire lasers, with a particular emphasis on their optical characteristics categorized in two groups: (1) waveguiding related properties in Section 3, which includes waveguide modes, near-field coupling, endface reflection, substrate-induced effects, and nanowire … Nettet29. sep. 2024 · The key dependence of the laser threshold on nanowire diam. is demonstrated and explained by a thorough study of guided modes in semiconducting nanowires for a nanowire-on-substrate geometry. A 'head on' detection geometry is used to measure the far-field profile of a nanowire laser and thus identify the modes …
NettetUnder nitrogen, nanowire lasing continues uninterrupted for longer than 1 h or over 10 9 excitation cycles (Fig. 3B, blue trace), with the nanowire undamaged after this time . Under atmospheric conditions, lasing output is observed to decrease over the course of the experiment, but it does not fall below the original output until over 4.4 × 10 8 … Nettetnanowire lasing are also of great interest both practically and theoretically. Stimulated emission in thin films of ZnO (band gap ) 3.3 eV) at room temperature was first observed in 1997,19 although the mechanism of the lasing was somewhat unclear. Random lasing in dense ZnO particulates has also been proposed
