TLDR
This work investigates electrically pumped, distributed feedback (DFB) lasers, based on gap-plasmon mode metallic waveguides, which have nano-scale widths below the diffraction limit and incorporate vertical groove Bragg gratings, and shows strong line narrowing and super linear light current curves for these plasmon Mode devices even at room temperature.Abstract:
We investigate electrically pumped, distributed feedback (DFB) lasers, based on gap-plasmon mode metallic waveguides. The waveguides have nano-scale widths below the diffraction limit and incorporate vertical groove Bragg gratings. These metallic Bragg gratings provide a broad bandwidth stop band (~500nm) with grating coupling coefficients of over 5000/cm. A strong suppression of spontaneous emission occurs in these Bragg grating cavities, over the stop band frequencies. This strong suppression manifests itself in our experimental results as a near absence of spontaneous emission and significantly reduced lasing thresholds when compared to similar length Fabry-Perot waveguide cavities. Furthermore, the reduced threshold pumping requirements permits us to show strong line narrowing and super linear light current curves for these plasmon mode devices even at room temperature.read more

Qing Zhang,Guangyuan Li,Xinfeng Liu,Fang Qian,Yat Li,Tze Chien Sum,Charles M. Lieber,Qihua Xiong +7 more
TL;DR: This work demonstrates the first strong room temperature ultraviolet SP polariton laser with an extremely low threshold and finds that a closed-contact planar semiconductor-insulator-metal interface greatly lessens the scattering loss, and more importantly, efficiently promotes the exciton-SP energy transfer thus furnishes adequate optical gain to compensate the loss.

TL;DR: It is shown that 44-nm-diameter nanoparticles with a gold core and dye-doped silica shell allow us to completely overcome the loss of localized surface plasmons by gain and realize a spaser, and that outcoupling of surface plasmon oscillations to photonic modes at a wavelength of 531 nm makes this system the smallest nanolaser reported to date—and to the authors' knowledge the first operating at visible wavelengths.
