Fig. 4: Comparison between plasmonic nanolasers and photonic nanolasers120.
a In total, 170 plasmonic nanolasers (top) and photonic nanolasers (bottom) were measured for comparison, each with the same gain material and cavity feedback mechanism. b–e Comparisons of cavity size (b), spontaneous emission lifetime (c), threshold (d) and power consumption (e). These comparisons suggest that plasmonic lasers can be more compact and faster with lower power consumption than photonic nanolasers when the cavity size approaches or surpasses the diffraction limit.
