Summary: A newly designed photonic crystal fiber based plasmonic sensor is proposed for label free biological analyte detection. By introducing scaled down air holes to create a light leakage channel and coating gold film and high refractive index TiO2 films outside the fiber periphery, the sensor achieves efficient sensing response.

This mixed state combines the advantages of rapid propagation and low effective mass from photonics with the desirable optical properties of TMDC exciton, such as nonlinearity and spin-valley polarization. As a result, it serves as an ideal platform for studying various physics phenomena and designing novel optoelectronic devices.
