Abstract


Fabrikasi dan karakterisasi directional coupler konfigurasi 3×3 planar berbahan serat optik plastik step index moda jamak tipe FD-620-10 telah dilakukan dengan panjang kupasan 35 mm, 40 mm, 45 mm, 50 mm, 55 mm, 60 mm dan 65 mm menggunakan pendekatan metode Fused Biconical Tapered (FBT) yang menghasilkan karakteristik yang berbeda. Hasil karakterisasi directional coupler konfigurasi 3×3 planar menggunakan BF5R-D1-N menunjukkan bahwa semakin besar panjang kupasan maka semakin besar rugi daya dan semakin kecil intensitas cahaya yang diteruskan. Pada directional coupler konfigurasi 3×3 planar dengan panjang kupasan 60 mm dan input pada Port B1 didapatkan nilai CR = 0.34 : 0.31 : 0.35 ; Le = -3.59 dB; Lins = -8.24 dB, -8.67 dB, -8.19 dB; dan D = -13.33 dB, -13.43 dB. Piranti ini paling baik digunakan sebagai pembagi daya maupun pemecah berkas sehingga selanjutnya dapat digunakan sebagai piranti dalam sensor.
