This manuscript reporting a unique Surface Plasmon Resonance (SPR) drew biosensor based on Photonic Crystal Fiber (PCF). The designed sensor can be utilized for the sensing of liquid analyte having a refractive index in range 1.40-1.45.The aforesaid sensor is showing wavelength sensitivity of as high as 37000 nm/RIU. The reported device can be a promising device for bio-sensing and chemical detection applications.
This work proposed a hexagonal spiral PCF based on SPR biosensor. This work report the phase matching resonance condition at 680 nm for the refractive index of 1.39 having confinement loss of 1.92x10-6 dB/cm.
