Long period fiber grating for biosensing: an improved design methodology to enhance add-layer sensitivity
No full textWe present our theoretical study on the design of
LPFG sensor where its add-layer sensitivity is enhanced. addlayer
sensitivity quantifies the sensitivity of the sensor to the
changes taking place within few tens of nanometers around the
receptor molecules. Two different methodologies: the use of dual
overlay layer and tailoring of the intermodal separation between
two cladding modes, have been used to enhance the add-layer
sensitivity. Using coupled mode analysis we compute several
examples to carry out a detailed comparative analysis between
the results obtained, focusing on the cladding mode near mode
transition.This work was supported by Council of Scientific Research (CSIR), India
