“…Arrayed waveguide gratings (AWGs) have been implemented in several materials and platforms such as silica, polymers, titanium dioxide, silicon nitride, and striploaded slot waveguides [1] - [5]. A silicon-on-insulator (SOI) wafer is however a fascinating platform for AWGs.…”

32-channel arrayed waveguide grating spectrometer (AWG) at 1800 nm is demonstrated on a 2-µm-thick silicon-on-insulator (SOI) platform. The design and simulation of the device are performed using the beam propagation method (BPM) and we obtain the 3-dB channel width, channel spacing, and extinction ratio of 1.16 nm, 1.56 nm, and 5.17 dB, respectively. The AWG demultiplexer can be applied in the central part of a spectrometer which is replacing in integrated optics a prism or a grating in conventional free-space optics.
