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.
