提出了一种新型的超紧凑阵列波导光栅（AWG）解复用器结构。目前的布局有两个重叠的自由传播区域，比传统的布局更紧凑。采用αSi-on-SiO2纳米线波导，制备了通道间距为11 nm的超小4×4 AWG（约40×50µm2）并进行了表征。
A novel layout for an ultra-compact arrayed-waveguide grating (AWG) demultiplexer is presented. The present layout has two overlapped free propagation regions, and is more compact than a conventional layout. Using αSi-on-SiO2 nanowire waveguides, an ultra-small 4×4 AWG (about 40×50 µm2) with channel spacing of 11 nm is fabricated and characterised.
