AbstractPlasmon lasers are a new class of coherent optical amplifiersthat generate and sustain light well below its diffraction limit. Their intense, coherent and confined optical fields can enhance significantly lightĝ€"matter interactions and bring fundamentallynew capabilities to bio-sensing, data storage, photolithography and optical communications. However, metallic plasmon laser cavities generally exhibit both high metal and radiation losses, limiting the operation of plasmon lasers to cryogenic temperatures, where sufficient gain can be attained. Here, we present a room-temperature semiconductor sub-diffraction-limited laser by adopting total internal reflection of surface plasmons to mitigate the radiation loss, while using hybrid semiconductorĝ €"insulatorĝ€"metal nanosquares for strong confinement with low metal loss. High cavity quality factors, approaching 100, along with strong λ/20 mode confinement, lead to enhancements of spontaneous emission rate by up to 18-fold. By controlling the structural geometry we reduce the number of cavity modes to achieve single-mode lasing. © 2011 Macmillan Publishers Limited. All rights reserved.
