Abstract
Perangkat serat optik telah menarik perhatian di bidang metrologi karena biayanya rendah, fabrikasi yang mudah, dan tahan terhadap interferensi elektromagnetik. Serat optik SMS telah banyak digunakan untuk berbagai aplikasi salah satunya adalah sensor suhu. Serat optik yang digunakan memiliki efek nonlinier. Efek nonlinier pada serat optik terjadi karena perubahan pada indeks bias medium dengan intensitas optik dan fenomena hamburan inelastik. Untuk lebih spesifiknya, melalui efek Kerr intensitas cahaya yang kuat dapat mengubah indeks bias medium dimana berkas sinyal merambat. Dalam penelitian ini dibandingkan karakteristik sensor suhu berbasis serat optik SMS dengan konsentrasi mol dan jenis material doping yang berbeda yaitu GeO2 (6,3%), B2O3 (5,2%), dan P2O5 (10,5%) dan diperhitungkan pengaruh efek Kerr jika digunakan cahaya berintensitas tinggi untuk rentang suhu 00C-1000C. Berdasarkan perhitungan numerik pengaruh efek Kerr terhadap karakteristik sensor suhu SMS dapat ditentukan sensitivitas sensor. Hasilnya, akibat dari efek Kerr, sensor suhu berbasis serat optik SMS memiliki sensitivitas yang semakin baik seiring dengan kenaikan intensitas cahaya yang diberikan. Sensitivitas yang paling besar berada pada intensitas cahaya 6,7x1012 W/m2 yaitu -0,068059 dB/℃ dengan wavelength shift sebesar -93,17 pm/℃.
=========================================================
Optical fiber devices have been utilized in the field of metrology because of their low cost, easy fabrication, and resistance to electromagnetic interference. Optical fiber SMS has been used for various applications, for example as temperature sensor. The optical fiber has a nonlinier effect. Nonlinier effects on optical fibers occur due to changes in the refractive index of the medium with optical intensity and the phenomenon of inelastic scattering. To be more specific, through the Kerr effect a strong intensity can change the refractive index of the medium where the signal beam propagates. In this study, the characteristics of optical fiber SMS as temperature sensor with different mole concentration and types of doping material GeO2 (6.3%), B2O3 (5.2%), and P2O5 (10.5%) and calculated the effect Kerr if high intensity light is used for the temperature range 00C-1000C. Based on numerical calculations the Kerr effect on the temperature sensor characteristics can be determined the sensitivity. As a result of the Kerr effect, the temperature sensor based on optical fiber SMS has improved sensitivity with the increase in the intensity of the light. The greatest sensitivity is at a light intensity of 6.7x1012 W/m2 that is -0.068059 dB/℃ with a wavelength shift of -93.17 pm/℃.
