We report simulation of a fibre optic sensors class of potential interest for various applications, namely Long Period Grating Fibre Sensors (LPGFS) having a graphene layer deposited on the cladding in the grating zone. Studied LPGFS consists of single mode (SM) fused silica optical fibre onto/into which a grating with 10 µm to 1000 µm is inscribed over a 5 mm to 75 mm length zone. During the simulations, the main issue of interest is the displacement of peak wavelengths and bandwidths broadening of the absorption bands corresponding to the energy transfer from core propagating mode to the possible cladding modes at the interaction with the grating as results of ambient medium different factors action.

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.
