Abstract

Telah dilakukan pengkarakterisasian sistem sensor serat optik berdasarkan efek gelombang evanescent. Karakterisasi dilakukan untuk melihat pengaruh panjang pengelupasan cladding terhadap rugi-rugi pada serat optik dan pengaruh pembengkokan serat optik yang telah dikupas cladding-nya terhadap rugi-rugi pada serat optik. Penelitian dilakukan dengan memvariasikan jenis cladding pengganti yaitu cladding udara dan air, memvariasikan panjang pengupasan cladding dengan panjang 3 cm sampai 10 cm, serta memvariasikan pembengkokan serat optik tersebut. Alat dan bahan yang digunakan adalah serat optik moda jamak FD-620-10, LED superbright warna merah ukuran 5 mm, detektor cahaya OPT 101 dan multimeter digital. Serat optik dipotong sepanjang 17 cm dan dikupas cladding-nya dengan menggunakan larutan aseton. Hasil eksperimen memperlihatkan bahwa semakin panjang pengupasan cladding, semakin besar rugi-rugi serat optik yang dihasilkan. Rugi-rugi serat optik juga akan semakin besar seiring bertambah besarnya pembengkokan serat optik. Pada kasus efek gelombang evanescent, nilai indeks bias cladding berpengaruh terhadap intensitas cahaya yang ditransmisikan dalam serat optik. Penurunan nilai indeks bias cladding akan membuat intensitas cahaya yang ditransmisikan juga akan menurun sehingga rugi-rugi serat optik menjadi besar.
