A novel 64-channel silicon hybrid demultiplexer is proposed and demonstrated by utilizing a 1×4 ADC-type mode demultiplexer and two 17×17 bi-directional AWGs. With the proposed design, the hybrid demultiplexer becomes very compact and this issue of the channel-wavelength’s misalignment is also relaxed greatly in comparison with the previous design. The insertion loss and crosstalk for the fabricated hybrid demultiplexer are around −5dB and −14dB, respectively.
