Tilted fiber Bragg gratings provide three interesting advantages in sensing:
1) access to surface waves on the cladding surface;
2) a resonant structure with high Q-factor spectral linewidths;
3) a built-in very accurate thermometer.
These features have been critical in the development of high performance sensors
for physical, chemical, and biochemical signals as well as process monitors for
nanoscale coatings of metals and dielectric materials for plasmonic applications.
