Abstract

Photonic crystal fibers (PCFs), although a highly effective platform for sensing, encounter difficulties with coupling as well as infiltration and evacuation. A PCF integrated microfluidic chip has therefore been fabricated to demonstrate improved coupling for real-time chemical sensing. Furthermore, an extremely sensitive dip-shifting analysis was employed for the detection regime. Results eventually demonstrated its notable sensitivity and a refractive index resolution of 10-7 RIU, rendering it suitable for utilization in highly sensitive sensing applications.
