“…Based on parameter setting from A, it is gives total length of FPR= 710.419 µm. The common Ushaped pattern is ideally suitable for narrow channel spacing with small value of free spectral range (FSR) and large value of ΔL, where typically hundreds of wavelengths [1]. The relation between FSR and ΔL are inversely proportional to each other [1].…”

“…Today's communication network technology requires high performance in terms of transmission capacity especially for local and metro area network (LAN/MAN) [2]. Hence, the great solution technology which can be used to increase the aggregate transmission on a single fiber used by LAN/MAN is Wavelength Division Multiplexing (WDM) [1]. WDM technology is divided into two systems namely dense WDM (DWDM) and coarse WDM (CWDM).…”

Silicon-on-insulator (SOI) has become one of the popular material that is widely used to develop passive or active devices in application for modern photonics communication. Using SOI, we proposed a new double S-shaped Arrayed Waveguide Grating (AWG) with broad channel spacing of 20 nm (~2500 GHz). This SOI-based AWG device performed with low insertion loss of <3.74 dB for a total of 16 channels where it covers the wavelength from 1311 nm to 1611 nm. The successful design of SOI-based AWG was then applied in CWDM system configuration where 10 Gb/s and 40 Gb/s data rates were used with optimized thermal noise inside the InGaAs pin photodiode and InGaAs Avalanche Photodiode (APD) at the system receiver. The maximum length of fiber was investigated for both photodetectors before the signal degraded when the bit error rate (BER) became worse than 10 -9 . Apparently, the distance of fiber can reach over 50 km when InGaAs APD was used for this system. Overall, this device that was developed on SOI material possibly increased the transmission capacity for application in metro access network.

“…Optical light beams couple if the distance between adjacent waveguides in the arrayed waveguide region is <3 μm. AWGs with an S-shaped pattern have also been used in other practical devices, 14 such as in broadband InP AWGs. However, the arrayed waveguide region was different when an antisymmetric S-shaped pattern was used.…”

A linear tapered double S-shaped arrayed waveguide grating (AWG) was designed as an alternative to a U-shaped AWG, and a complete transmission spectrum for 18 channels of coarse wavelength-division multiplexing (CWDM) was demonstrated. The silicon-on-insulator based AWG with a rib waveguide structure with a broad channel spacing of 20 nm was designed to serve as a multiplexer/demultiplexer. A beam propagation method modeling simulation under transverse electric mode polarization over a free spectrum range of 700 nm was used for the design process. The geometrical dimensions of the AWG rib structure were optimized to achieve the lowest reported insertion loss of 1.07 dB and adjacent crosstalk of −38.83 dB. The influence of different etching depths on the top Si layer of the AWG for a constant core width of 0.6 μm as well as birefringence effects were also investigated. A transmission spectrum response at the output port close to the standard CWDM wavelength grid range of 1271 to 1611 nm with an average channel spacing of 2485 GHz was obtained. IntroductionSilicon-on-insulator (SOI) has become a popular choice of material in recent years because of its potential for use in the photonics components manufacturing industry, which uses a monolithic or hybrid integration assembly. Arrayed waveguide gratings (AWG)-based silicon waveguide structures functioning as multiplexers/demultiplexers (mux/ demux) are being widely employed in wavelength-division multiplexing (WDM) systems. There are several advantages in using SOI as a platform for photonics integration, such as low manufacturing costs due to the use of existing complementary metal oxide semiconductor fabrication technology, 1 compact devices, and high confinement of the optical mode. 2 Further, silicon has a high index contrast (Δn) and is transparent at infrared wavelengths, making it suitable for optical communication applications. By using these features of SOI materials, we designed and analyzed an SOI-based AWG mux/demux capable of splitting or combining the multiple signals in a single fiber utilized in coarse wavelength-division multiplexing (CWDM) systems.In this work, we optimized the geometrical rib waveguide structure and characterized the ideal parameters of a linear tapered double S-shaped AWG on an SOI platform to mitigate insertion loss (IL) and adjacent crosstalk (XT) in an 18-channel CWDM device with a channel spacing of 20 nm. The investigations were carried out by selecting the dimensions of the rib waveguide, which allows a single-mode condition where the ratio of the slab height (h) to the thickness of the top silicon (Si) guiding layer (H) or h∕H was in the range
