Abstract

Base on Silicon-On-Insulator (SOI), we demonstrate and compare three O-band 8-channel (de-)multiplexers based on box-shaped AWG, freeform-shaped AWG and saddle-shaped AWG for the 400 GBASE-LR8 norms. The comparison results indicate that the box-shaped AWG with large channel crosstalk of 23.3 dB, well-matched channel spacing and the FSR is more advisable choice for the 50 Gb/s PAM4 signal adopted by the 400 GBASE-LR8 standards with bandwidth of 0.14 nm.
