In this method, the bandpass filter (BPF) was utilized as a reference element and fibre Bragg grating (FBG) served as a sensing element. The wideband light is equally split and launched to sensing and reference elements. The reflected light of sensing element coherently interferes with the output of BPF inside 3-dB coupler. A photodiode detects the interfered signal and the beat frequency can be determined to achieve a high-resolution. To examine the proposed method, the scheme for temperature sensing is investigated. The Fabry-Perot narrow-bandpass filter type (F7 glass) serve as BPF. The results reveal that a good and fast response to temperature change with the sensitivity of 1.152 GHz/ oC can be obtained. 2020-06-23T04:40:03Z 2020-06-23T04:40:03Z 2020-04 Article International Journal of Nanoelectronics and Materials, vol.13(2), 2020, pages 241-248 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/65167 http://ijneam.unimap.edu.my en Universiti Malaysia Perlis (UniMAP)
