Phase Errors in mid-IR Arrayed Waveguide Gratings based on graded index SiGe-Si technology

Ainur Koshkinbayeva, Regis Orobtchouk, Pierre Labeye

In this paper, we present a method for analysis of phase errors and power truncation in SiGe/Si graded index arrayed waveguide gratings (AWGs) operating in mid-infrared spectral ra…
