Photonic crystal nanocavity with high Purcell factor

Theoretical realization of ultra-huge Purcell factor design of photonic crystal nano-cavity has been reported in this article. Considerably enhanced value of Purcell factor PF = 91*10^6 achieved at resonant wavelength of 1.55 µm, originates from choosing optimized and modified geometrical parameters of the structure. Strong improving the light-matter interaction, our device is directly proportional in integrated optics to realize interacting coupled systems.
