An efficient hybrid photonic-plasmonic structure which combines the resonant mode of an ultrahigh Purcell factor photonic crystal nano-cavity with plasmonic resonance of a bowtie nano-antenna with a high accuracy has been presented in this article. The consequential enormous light intensity enhancement of ~3×106 times in the gap region of the bowtie nanoantenna (in the coupled structure with respect to the incoming exciting light), originated from the effective optical resonance combination, is realized by subtle optimization of nano-cavity’s geometrical parameters. The designed coupled structure holds great promise for many applications and purposes trusting on strong confinement and enhancement of o ptical field in the volumes of nano-scale, including antennas, optical trapping and manipulation, sensors, data storage, nonlinear optics, lasers, etc.
