Design, process and characterization of an arrayed waveguide grating in the 2180–2280cm−1 range

Abstract

In this paper, we present the design, process and characterization of an AWC bused on a SiGe graded index waveguide plateform, operating at 4.5μm (2180-2280cm-1). A transmission of -5dB and a crosstalk below -20dB arc demonstrated.
