DWDM (Dense Wavelength Division Multiplexing) adalah suatu teknik multiplexing yang mampu mentransmisikan lebih dari 400 panjang gelombang dalam satu serat optik. Laju pengiriman data menggunakan media serat optik dapat mencapai 1 Tbps atau 1.000 Gbps. DWDM merupakan suatu perbaikan dari WDM. Inti perbaikan yang dimiliki oleh teknologi DWDM terletak pada jenis filter, serat optik dan penguat amplifier. Jenis filter yang umum dipergunakan salah satunya adalah  Array Waveguide Grating  (AWG).  Pada Penelitian ini dianalisis kinerja suatu Array Waveguide Filters (AWG) yang mampu digunakan pada DWDM.  Pada Penelitian ini dilakukan dengan menggunkan 2 software. Pertama, menggunakan software Optisystem 7 untuk memodelkan sistem DWDM. Kedua, menggunakan software OptiBPM untuk verifikasi AWG. Pada Optisystem didapatkan nilai konfigurasi DWDM yang optimal yaitu pada C Band dengan spasi kanal 50GHz dan jumlah wavelength 64. Sedangkan pada OptiBPM didapatkan untuk konfigurasi DWDM tersebut diperlukan AWG dengan dengan sudut orientasi 53 derajat, panjang FSR 1500um, lebar angular 11,4 derajat dengan ukuran 15000x10000um sehingga didapatkan nilai BER, Q-factor dan crosstalk yang memiliki perbedaan namun telah mencapai kriteria  yaitu dengan Q factor antara 8,43 sampai dengan 14,09 sedangkan untuk BER dari 1,719x10-40 sampai dengan 1,19x10-17 dan crosstalk antara -149 dB sampai dengan -40,8 dB.

Wdm Pon

The simulation diagram of WDM-PON is proposed, utilizing DFB laser diodes as light sources, array waveguide grating as multiplexer for signals’ split and amplifiers as gain generator, respectively, to realize networking for both sending and receiving units. WDM-PON system with 128 branches service signals and transmission rate of 210Gb/s is finally simulated and the system performances are analyzed and discussed.

In this work, thermo-optic (TO) lateral shift apodized sampled waveguide grating for 1550 nm wavelength is designed and fabricated by the metal-printing technique based on fluorinated epoxy-terminated polycarbonates (FBPA-PC EP) and fluorinated epoxy resin (FSU-8) materials. The optical characteristics and thermal stability of the FBPA-PC EP and FSU-8 materials are analyzed. To realize periodic wide-spectrum filtering and suppress the side-lobes of grating, a lateral shift apodized sampled waveguide grating is proposed. The 3 dB bandwidth and wavelength spacing can reach 4.8 nm and 9.7 nm. The side-lobe suppression ratio of proposed device can reach 22.6 dB, which is much better than traditional Bragg grating (6.1 dB). Driving electrical powers of 42.4 mW and 87.2 mW can produce blueshifts of 1.8 nm and 3.5 nm in the measured reflection spectrum, respectively. This device realizes the aim of multiple functions, including periodic filtering, wide-spectrum filtering, and high side-lobe suppression. The device is applicable of realizing signal processing and wavelength division multiplexing (WDM )systems.

We propose and demonstrate a simple water level monitoring system based on the wavelength division multiplexing (WDM) for the spent fuel pool (SFP) at a nuclear power plant. The basic principle is based on the measurement of the optical power spectra by the Fresnel reflection according to the change of the refractive index at the end facet of the optical fiber tip (OFT). An arrayed waveguide grating (AWG) is employed to achieve multi-channel sensing capability with a C-band broadband light source (BLS) based on amplified spontaneous emission (ASE). The feasibility of the proposed scheme is investigated with a simulation and experimentation. We also investigate the limiting factor for remote transmission. The system performance is degraded by the Rayleigh backscattering of the BLS light, but it can be operated over long distances within 10 km with 5 dB of difference peak power margin.
