Resumen
We 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 ...

We 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. [--]
