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.
