Paper Abstract
Bragg grating refractometers have been previously disclosed by other authors but sometimes suffer from temperature instability due to well know grating characteristics. In order to overcome this limitation, a temperature insensitive refractometer is developed by using a cladding mode resonance as a temperature reference, with the relative shift of the core mode resonance used to measure the refractive index of substances under test. Specifically, the device fabricated here produces a relative resonance shift of 1 pm for every 5×10-4 of measured index change, with a temperature sensitivity less than 0.5 pm/°C.
