Comparison of Silicon Lattice-Filter-Based O-Band 1×8 (De)Multiplexers With Flat and Gaussian-Like Passbands

Comparison of Silicon Lattice-Filter-Based O-Band 1×8 (De)Multiplexers With Flat and Gaussian-Like Passbands

Based on cascaded Mach-Zehnder interferometer (MZI) lattice filters, we demonstrate and compare silicon O-band 8-channel (de-)multiplexers with flat and Gaussian-like passbands for the 400 GBASE-LR8 norm. The 1×8 (de-)multiplexer with flat passbands exhibit insertion loss less than 2.5 dB...
