Temperature compensated long-period gratings for biochemical sensing applications

A novel temperature compensation method for long-period grating (LPG) based biochemical sensor is proposed and experimentally demonstrated. Special laser-heated fiber (LHF) is used for fabricating LPG sensor whose temperature cross-sensitivity can be compensated by laser heating. Experimental results show that such a method is very promising for biochemical sensing and can be used to compensate temperature variation of ∼86 °C.
