Monolithic 1 × 8 DWDM Silicon Optical Transmitter Using an Arrayed-Waveguide Grating and Electro-Absorption Modulators for Switch Fabrics in Intra-Data-Center Interconnects [PDF]
Micromachines, 2020 In this study, we propose an eight-channel monolithic optical transmitter using silicon electro-absorption modulators (EAMs) based on free-carrier injection by Schottky junctions. The transmitter consists of a 1 × 8 silicon arrayed-waveguide grating (AWG)

JAREE (Journal on Advanced Research in Electrical Engineering), 2018 Arrayed Waveguide Grating (AWG) Technology, one technique of dividing the channel into smaller sub-channels by adjusting the fixed array length increment. AWG techniques can generate coherent transmissions, which are suitable for Wavelength Division Multiplexing (WDM), to be implemented as multiplexer, demultiplexer, filter, add-drop device, and more ...

Electronics Letters, 2000 We propose a new low loss groove design for athermal silica-based arrayed-waveguide grating multiplexers. The insertion loss was 3 dB and the cross talk was -35 dB. The temperature dependence of the channel wavelength change was suppressed to below 0.4 nm in the 0-85/spl deg/C temperature range.

Arrayed-waveguide-grating light collector for on-chip spectroscopy [PDF]
, 2010 We present a novel arrayed-waveguide-grating (AWG) device with improved external (biomedical) signal collection for use in on-chip spectroscopy. The collection efficiency of the device is compared to that of a standard AWG.

, 2005 This thesis proposed and demonstrated a flat-spectral response Arrayed Waveguide Grating (AWG) in Silicon-on-Insulator (SOI). The response exhibits a flat spectral of approximately 0.5nm with a crosstalk level of round -3dB. The high crosstalk is due to the phase errors as a result of fabrication tolerance and errors.
