Abstract

Teknologi Arrayed Waveguide Grating (AWG), salah satu solusi membagi kanal menjadi sub kanal lebih kecil dengan mengatur selisih panjang array tetap. Teknik AWG bisa menghasilkan transmisi koheren, yang cocok untuk wavelength division multiplexing (WDM), baik sebagai multiplexer, demultiplexer,filter, add-drop device, dan lainnya. Dalam Tugas Akhir ini, dilakukan perencanaan desain parameter AWG beroperasi pada kanal C-Band (1530-1560 nm), untuk mendukung kebutuhan kanal WDM, baik coarse-WDM (CWDM), dense-WDM (CWDM) maupun very high density-WDM (VHDWDM). Perencanaan dilakukan lewat perhitungan teoritis dan menggunakan bantuan tool berupa WDM_Phasar. Perhitungan parameter AWG secara teoritis bertujuan menghasilkan parameter desain ideal, sementara lewat WDM_phasar dengan menambahkan batasan ukuran devais, crosstalk dan nonuniformity, diharapkan akan diperoleh parameter desain yang lebih realistis. Adapun parameter yang diamati meliputi besarnya orde difraksi (m), panjang free propagation range (FPR), perbedaan panjang array (ΔL), jumlah array (Narray), jumlah kanal I/O (Nmax) dan free spectral range (FSR). Dengan contoh spasi kanal 100 GHz pada C-band, dihasilkan parameter hitungan teoritis sebesar 1308,61 μm, 25,1698 μm, 43,7143, 108 buah, 27 kanal dan 21,211 nm, masing-masing untuk nilai FPR, ΔL, m, Narray, Nmax dan FSR. Sedangkan lewat bantuan WDM_Phasar dengan batasan ukuran devais (15000x9000 μm2), crosstalk (-35 dB) dan nonuniformity (0,5), menghasilkan parameter AWG 1197,347 μm(FSR), 23,764 μm(ΔL), 41(m), 56 (Narray), 16(Nmax) dan 11,2 nm(FSR). Semakin besar spasi kanal, jumlah bit yang bisa diangkut juga semakin banyak ======================================================================================================= Arrayed waveguide Grating (AWG) technology is one solution divides the channel into sub-channels, the smaller the margin set fixed array length. The AWG technique can produce coherent transmission, which are suitable for wavelength division multiplexing (WDM), either as a multiplexer, demultiplexer, filters, add-drop device and so on. In this final project, planned the design parameters of the AWG operates on C-band channel (1530-1560 nm), to support the needs of WDM channels, both coarse-WDM (CWDM), dense-WDM (CWDM) and very high-density WDM (VHDWDM). AWG design planning is done through theoretical calculations and use a tool assistance such WDM_Phasar. AWG theory parameter calculation is purpose in order to produce an ideal design parameters, while WDM_phasar by adding device size limitations, crosstalk and nonuniformity, is expected to be obtained more realistic design parameters. The parameters include the magnitude of the observed diffraction order (m), free propagation length range (FPR), the array length difference (ΔL), the number of arrays (Narray), the number of channels of I / O (Nmax) and the free spectral range (FSR). Taking the example of a 100 GHz channel spacing in C-band, after the calculation of the theoretical yield AWG parameters of 1308.61 μm, μm 25.1698, 43.7143, 108 pieces, 27 channels and 21.211 nm, respectively for the value of FPR , ΔL, m, Narray, Nmax and FSR. While passing WDM_Phasar assistance device size limit (15000x9000 μm2), crosstalk (-35 dB) and nonuniformity (0.5), generate parameter 1197.347 μm AWG (FSR), 23.764 μm (ΔL), 41 (m), 56 (Narray), 16 (Nmax) and 11.2 nm (FSR). The larger the channel spacing , the number of bits that can be transported also increased.
