Fig. 7: Characterization of MZI based multi-wavelength multi-port source.
From: Integrated multi-port multi-wavelength coherent optical source for beyond Tb/s optical links
a Measurement setup. The optical comb is coupled to the MZI-based 1:8 DeMux, and a fraction of each output is coupled off-chip and captured by an optical spectrum analyzer. b Microphotograph of the MZI-based DeMux chip. c Normalized spectra of 8 DeMux outputs, where at each output, one in every 8th comb lines are selected.
