“…Variable optical attenuator (VOA) is a device that functions to adjust optical power in the optical devices interconnection system. Few types of VOA structure have been developed; for example Mach-Zehnder interferometer (MZI) based VOA [1][2][3], straight waveguide based VOA [4][5][6] and multimode interference (MMI) based VOA [7][8]. From the survey on type of developed VOA, it shows that the MMI structure have the smallest power consumption; 7.8mW [8] compared with other type of VOA structure.…”

Sebuah desain struktural baru yang menggabungkan atenuator optik variabel (VOA) dan saklar optik diusulkan dalam makalah ini. Desain didasarkan pada arsitektur interferensi multimode (MMI) dan desiain ini telah menunjukkan peningkatan crosstalk saklar optik. Perangkat beroperasi dengan memanipulasi efek optik-termo (TO) yang secara alami ada di semua materi pemandu-gelombang optik. Dengan menerapkan suatu polimer pada platform material kaca, VOA dioptimalkan dengan pelemahan optik 21,52 dB telah dicapai dengan daya 36,4 mW. Hasil simulasi menunjukkan bahwa VOA membantu untuk mencapai perbaikan yang signifikan kinerja saklar optik khususnya di pengurangan crosstalk hingga 89,66%.

AbstrakSebuah desain struktural baru yang menggabungkan atenuator optik variabel (VOA) IntroductionHigh speed and high capacity optical components are crucially needed in current optical networks. For this, it is very necessary to research for good and tolerable performances of optical switch. Furthermore, it is important to develop optical devices with low power consumption and crosstalk. Interestingly, multimode interference (MMI) structure is a good candidate for these purposes. Although numbers of MMI optical switches have been developed which progressively claimed low switching power results, the crosstalk issue is yet to be solved.Variable optical attenuator (VOA) is a device that functions to adjust optical power in the optical devices interconnection system. Few types of VOA structure have been developed; for example Mach-Zehnder interferometer (MZI) based VOA [1-3], straight waveguide based VOA [4-6] and multimode interference (MMI) based VOA [7][8]. From the survey on type of developed VOA, it shows that the MMI structure have the smallest power consumption; 7.8mW [8] compared with other type of VOA structure. Obviously, the MMI structure is a good candidate for VOA design.For MMI-VOA structure, there two types of VOA that have been develop previously which are; a combination of two MMI structure to be operate as MZI-VOA [9] and single MMI-VOA [10]. In the MZI-VOA, the structure is composed of an MMI power splitter with single inputs and re-combined with double output to the other MMI combiner with single output. The active region (induced by electro or thermo effect) is located at the phase shift arms and used to change the relative phases among the arms, which can realize the attenuation function [11]. Concurrently, a single coupler of MMI-VOA is realized through refractive index modulation. The refractive index modulation leads to the variation of the imaging intensity within the MMI region. As a result, the output images can be attenuated which further realize the attenuation function.
