a Micrograph of a 5-channel dense wavelength division multiplexing (DWDM) Si MRM array. b Measured transmission spectrum of the 5-channel Si MRM array. c–g Measured eye diagrams of 200 Gb/s pulse amplitude modulation with four levels (PAM4) of channel 1, channel 2, channel 3, channel 4, and channel 5 (C1-C5). h Measured channel crosstalk of the DWDM MRM array.
