Merging photonic wire lasers and nanoantennas

One of the main goals of photonic integration is to combine different components that are capable of executing different functions. One of these functions is the generation of light: in this sense, photonic wire lasers may become a key component in future generations of integrated circuits because of their small footprints. Another is the generation of high-intensity electric fields that can be used to excite nonlinear effects, such as surface-enhanced Raman scattering, or to visualize nano-objects, in small regions and can be achieved by using plasmonic nanoantennas. In this paper, the combination of photonic wire lasers and plasmonic nanoantennas is examined. We show that a very compact photonic wire nanoantenna laser, which generates a high-intensity electric field inside the nanoantenna, can be produced.
