چكيده فارسي :
A huge enhancement of the light intensity in the gap vicinity of a bowtie nano-antenna in 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 is demonstrated. The consequential enormous light intensity enhancement of 12×106 times in the gap region of the bowtie nano-antenna, originated from the effective optical resonance combination, is realized by precise optimization of the nano-cavity’s physical parameters. The predominant feature of the designed coupled structure is generation of deeply subwavelength intense optical sources which hold great promise for many applications and purposes trusting on strong confinement and enhancement of optical field in the volume of nano-scale, including sensors, lasers, nonlinear optics, optical trapping, etc.
