2018年1月1日 · The filter routing rule of array waveguide grating (AWG) is applied for the wavelength channels (WCs) that need to be added and dropped by using the corresponding tunable fiber Bragg gratings (FBGs). The other WCs pass through output by tuning FBG filter spectra away from the WCs.

2018年8月29日 · Abstract: A routing device with N /2 2 × 2 optical cross-connectors (OXCs) is based on a pair of N x N cyclic array waveguide gratings (AWGs) and multiple tunable fiber Bragg gratings (FBGs) to realize the dense wavelength-division …

摘要:基于低损耗氮化硅光波导平台,采用一个1×6 阵列波导光栅(AWG)与六个仅中心波长不同的1×25AWG 两级级联的架构,优化设计了集成光谱分析芯片。 仿真结果表明,该光谱分析芯片的工作带宽、波长分辨率、最小通道插损分别为75 nm、0.5 nm 和4.9 dB,且通道间最小相邻、非相邻串扰约为-27.7 dB、-23.0 dB,最大相邻、非相邻串扰约为-22.6 dB、-12.5 dB。 小尺寸、高分辨率和大工作带宽光谱仪在各种应用中需求量很大,包括光谱学、医学成像、天文学、农业、食品工业 …

We propose a cyclic NxN AWG router that can multi/demultiplex upstream and downstream signals with different channel spacings in different wavelength regions. We fabricated a 4x4 AWG router for our novel λ-tunable WDM/TDM-PON using silica-based PLC technology and showed that it can cyclically multi/demultiplex both 20 nm-spaced and 200 GHz ...
