In this paper, a two-dimensional photonic crystal ring resonator based sensor is proposed and designed to detect the glucose concentration in urine over the range of 0gm/dl-15gm/dl. The proposed sensor is consisted of two inverted ＂L＂ waveguides and a ring resonator. If the glucose concentration in urine is varied, the refractive index of the urine is varied, which in turn the output response of sensor will be varied. By having the aforementioned principle, the glucose concentration in urine, glucose concentration in blood, albumin, urea, and bilirubin concentration in urine are predicted. The size of the proposed sensor is about 11.4μm×11.4 μm, and the sensor can predict the result very accurately without any delay, hence, this attempt could be implemented for medical applications.展开更多
