Abstract

Plasmonic lasers advance To push the physical limitations of lasers to the nanoscale regime it is necessary to tackle the fundamental challenge of surpassing the diffraction limit. It has been suggested that surface plasmons — light–matter waves trapped on the surface of a conductor — can be used to tightly confine light on very short length scales, but such approaches have been previously hampered by severe losses. Oulton et al. now demonstrate that it is possible to circumvent this problem by utilizing a hybrid between a dielectric waveguide and a conducting surface supporting a plasmon mode, thereby showing the experimental realization of a nanoscale plasmonic laser with an optical mode a hundred times smaller than the diffraction limit. Such hybrid plasmonic coherent light sources offer the possibility to explore extreme interactions between light and matter, and may open important new avenues in optoelectronics.
