Abstract In this article, a Quasi D-Shape dual core Photonic Crystal Fiber Surface Plasmon Resonance sensor is offered and numerically analyzed. The offered model is established comprising of circular air holes having an external sensing polishing layer coated with gold (Au) in order to ensure simple and straightforward design. The performance parameters are examined by means of modal analysis incorporated finite element method utilizing COMSOL multiphysics software. The sensor performance is analyzed with modifying the geometrical parameters like metal (Au) layer and pitch. It is observed; this model shows maximum amplitude sensitivity of 230 R IU−1 and wavelength sensitivity of 15,000 nm-RIU−1 incorporating amplitude interrogation method and wavelength interrogation method, respectively. The Figure of Merit is similarly considered and measured to 45 per RIU inbetween the refractive index ranging 1.42 RIU to 1.46 RIU. As a final point, a comparison has been given among the work explained in this paper with existing works. Keywords Quasi D · Dual core · Sensitivity · SPR · PCF

1 Introduction Over the past few decades, optical sensing technology attracted the researcher’s kind attention in different fields such as bio-imaging, bio-medical investigation, bio-engineering, and environmental observations (Rifat et al. 2017). In current years, PCF based SPR sensing instrumentation has been considered as leading technology by the reseachers (Hossain and Rana 2016a; Hossain et al. 2019a). In addition, SPR has been an intelligent research topic from the last 20 years because of its real-time detection and monitoring, non-invasive, high sensitivity and label-free processing in the field of security (Sarker et al. 2020; Islam et al. 2020), biochemical detection, biomedical diagnostics such as cancer detection (Saha et al. 2019a, 2020), optical solar cell, analysis of biomolecule interactions for
