Abstract
This Photonic sensing technology is a new and accurate measurement technology for bio-sensing applications. In this paper, a two-dimensional photonic crystal micro cavity ring resonator based sensor is proposed and designed to detect the glucose concentration in urine over the range of 0 gm/dl-15 gm/dl. The optical properties of glucose in urine are studied and average value of refractive index for different samples is taken as input. The change in the output transmission spectra and Q factor has been observed with the change in the concentration of glucose in urine and thus by capturing these changes the concentration of glucose in urine has been detected. The size of the proposed sensor is ultra compact in size about 6.42 μm×7.27 μm, and the sensor can predict the result very accurately without any delay, hence, this attempt could be implemented for medical applications.
