摘要

In a recent scenario, sensor technology is attractive and promising for industrial applications. The microstructure-based sensors are preferable due to their outstanding performance, compact size, fast response, accuracy, and wide range of availability. Photonic crystal fiber (PCF) fulfills the demand to develop such a sensor. This article proposed an elliptical air hole-based photonic crystal fiber (EH-PCF) with a circular ring at the core filled with platinum for temperature and refractive index sensing applications, simultaneously. The proposed design displays the mode field density of -8.86e-14 w/m at the core, and two transmittance dips of -88 dB are obtained at 1.53 mu m and similar to 1.56 mu m wavelength after simulation results. One of the significant factors that affect the sensitivity of the sensor is mode confinement loss that is 6.5x104 dB/cm at 1.55 mu m wavelength. The proposed sensor shows a sensitivity of 77 nm/degrees C for the temperature range of 20-160 degrees C and refractive index (RI) sensing in the range of 1.43 to 1.49 indicated the sensitivity of 1600 nm/RIU. Due to the complex RI, the ultranarrow bandgap is between the 0.10 to 0.11 frequency (w/2pic) for surface plasma resonance signals. The fabrication of the proposed design is a simple, low-cost method and will be significantly suitable for integrated photonics, nanotechnology, industry 4.0, temperature sensing, and biomedical applications.
