Over the past decade, solid‐state cholesteric liquid crystals (CLCsolid) have emerged as a promising photonic material, heralding new opportunities for the advancement of optical photonic biosensors and actuators. The periodic helical structure of CLCsolids gives rise to their distinctive capability of selectively reflecting incident radiation, rendering them highly promising contenders for a wide...
We demonstrate refractive index measurement of liquids using two sensor system designs, both based on microring resonators. Evanescent sensors based on microrings utilize the resonating nature of the light to dramatically decrease the required size and sample consumption volume, which are requirements of lab-on-a-chip sensor systems. The first design, which utilizes an optical microsphere, exhibits...
