A new plasmonic bowtie nanolaser structure is fabricated where a semiconductor gain core is enclosed by a metal shell with bowtie cross section built-in. Light emission characteristics under electrical injection will be reported.
We show that Bragg gratings can be readily incorporated into metallic nano-lasers which exploit waveguides with semiconductor cores, via modulation of the waveguide width. This provides a simple way to implement laser wavelength control.
We systematically characterized semiconductor-metal core-shell plasmonic nanolasers of various sizes and shapes under electrical injection. New experimental results will be presented including detailed temperature-dependent and duty cycle dependent performance measurements, as well as polarization measurements.
Metallic nano-cavities employed in recently demonstrated metallic cavity nano-lasers are examined. An overview is given of results from devices employing metal-insulator-metal structures with sub-wavelength dimensions, and progress in further miniaturization to tens of nanometers reported.
The modelling, fabrication and operation of recently demonstrated lasers employing metallic nano-cavities will be examined in this presentation. An overview will also be given of latest results from devices employing metal-insulator-metal structures with sub-wavelength dimensions. Finally future development directions, challenges and prospects for such lasers will be discussed.
In this letter, we demonstrate electrically pumped continuous-wave lasing at room temperature in microring lasers, which employ a quantum-dot gain medium. Lasing occurs in the important 1.55-mum telecom wavelength range. The 2-mum-wide ring waveguides are made from InGaAsP-InP (100) material suitable for active-passive photonic integrated circuits. Lasing in rings down to 22 mum in diameter is found,...
