A novel silicon photonic CWDM filter design is proposed and experimentally demonstrated. The design has achieved flat-top transmission across all dies on a wafer, with a device footprint of 48*25 {\mu}m2, an insertion loss of 0.24 $\pm$ 0.18 dB, and a channel central wavelength standard deviation of 0.77 nm.
