Paper Abstract

A novel sensing scheme to measure strain and temperature simultaneously by using an off-axis single mode-multimode-single mode (SMS) fiber optical structure is proposed in this article. The dual-parameter measurement is achieved based on the obviously different strain and temperature responses of two loss peaks in the off-axis SMS transmission spectrum. In experimental, the sensitivities value of temperature and Strain of two loss peaks are measured to -8.2pm/με, -2.3 pm/με and 41.2pm C ° / , 16.0pm C° / , respectively.
