| Description |
We propose a GeO(2)-P(2)O(5)-codoped step index multimode (SIMM) fiber having a core diameter of around 50 mu m with numerical aperture of around 0.21-0.22. The proposed SIMM fiber shows excellent linear radiation response behavior with sensitivity of around 0.69-0.97 dB/m/100 rad at a 505 nm wavelength within the dose rate range of 10-100 rad/h, as well as very low recovery at room temperature using a (60)Co gamma radiation source. This enables its practical application in fiber optic personal dosimeters for measurement of low dose gamma radiation. (C) 2011 Optical Society of America
