Abstract

Telah dikaji suatu filter add-drop yang terdiri dari suatu papah directional coupler, dimana salah satu lengannya dibuat suatu Bragg tunggal. Perhitungan didasarkan pada persamaan moda tergandeng yang dibuat dalam bentuk persamaan matriks, dengan mempertimbangkan struktur yang dikaji. Dari persamaan matrik, diperoleh faktorfaktor propagasi sebagai nilai eigen dari modus-eigen, sedangkan struktur ruang dari modus-eigen ditentukan dengan vektor-vektor eigen dari matrik tergandeng. Output dari filter add-drop, kerugian balik dan transmisi total dihitung dengan menggunakan syarat-syarat batas dalam masing-masing pandu gelombang pada panjang gelombang Bragg 1550 nm. Hasil yang diperoleh memenuhi persayaratan untuk aplikasi Wavelength Division Multiplexing (WDM) dalam sistem telekomunikasi. An add-drop filter that consists of a planar directional coupler with a single Bragg grating in one of its arms was studied. The calculation was based on coupled-mode equations in the form of a matrix equation by considering the studied structure. From the matrix equation, the propagation factors as eigenvalues of the eigenmodes was obtained, while the spatial structures of the eigenmodes are determined by the eigenvectors of the coupling matrix. By use of boundary conditions in individual waveguides, the drop output, return loss and total transmission, respectively, was calculated at the Bragg wavelength of 1550 nm. The results satisfy the requirements for Wavelength Division Multiplexing (WDM) applications.
