Abstract:
The characteristics of length-apodized phase-shifted fiber optic long period
gratings with full and partial nanostructured coatings have been explored
theoretically and experimentally. The twin rejection bands that are
characteristic of length-apodized phase-shifted long period gratings are studied
for a long period grating (LPG) operating at the phase matching turning point.
When one half of the length of the LPG is coated, complex bandgap like structure
appears within the transmission spectrum, which may be of benefit to spectral
filter design and for sensing applications.
