초록
We have investigated a temperature sensor on a thermal expansion effect of a fused optical fiber coupler. Both side of the fused tapered region of the coupler were fixed on a metal support to induce the high thermal expansion effect. The sensor showed that thepeak coupling wavelengths were shifted to shorted wavelength region with increased of environmental temperature. The sensitivity ofthe sensor was 0. 12 nm/oC.
