In the presented paper, we propose a sensing design of a photonic crystal fiber based on plasmonics finding its suitability to measure the variation in the refractive index of the analyte under consideration. The parameters such as sensitivity, reflectivity, confinement loss and birefringes play a vital role for a sensor suitable to measure various physical quantities in real life applications. The proposed sensor design is numerically investigated to analyze sensitivity, reflectivity, confinement loss and birefringes making it suitable for various sensing applications. The sensor exhibited high birefringes value 0.021401, which is recorded to be best for the sensitivity of a given sensor for the analytes depicting refractive index of 1.35. The higher values of birefringes accomplished with higher sensitivity and reduced values of nonlinearity makes the sensor suitable for numerous sensing applications. The design proposed can be easily fabricated making it cost effective along with ease of handling. The lowest confinement loss observed was 11.818 db/m. At refractive index of 1.4, this minimum loss making it suitable for sensing multifarious biological and chemical materials.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
