### Abstract

Quality factor and refractive sensitivity are significant parameters in designing optical devices such as filters, demultiplexers, switches and sensors. In this paper, we proposed a novel structure for photonic crystal ring resonator with octagon-shaped core. The transmission efficiency of the proposed ring resonator at $$\lambda =1551\,\hbox {nm}$$ λ = 1551 nm is about 99.6 % with bandwidth and quality factor values equal to 0.3 nm and 5170. The proposed structure is very sensitive upon the variation of refractive index of total structure and core part of the resonator, such that the refractive index sensitivity to the refractive index of total structure and the resonant ring core is $$\Delta \lambda /\Delta \lambda =3.1\,\hbox {nm}\,/\,0.01$$ Δ λ / Δ λ = 3.1 nm / 0.01 and $$\Delta \lambda /\Delta \hbox {n}=2.9\,\hbox {nm}\,/\,0.01$$ Δ λ / Δ n = 2.9 nm / 0.01 , respectively.
