Abstract
In this work, we report on the modeling and the experimental characterization of a 6×400 GHz silicon ArrayedWaveguide Grating (AWG). The design of the device is based on the reduction of the background noise. The goodcharacteristics of the AWG demonstrate that unwanted reflections have a detrimental role on its performance.We demonstrate a smoothing of the output channel shape of the AWG, as well as a reduction of the crosstalklevel from−20.6(1) dB to−24.4(1) dB.| File | Dimensione | Formato | |
