Abstract

A flat band-pass photonic filter is experimentally demonstrated on a silicon-on-insulator (SOI) substrate. The filter is composed of a micro-ring resonator assisted with an asymmetric Mach-Zehnder interferometer (MZI). By thermal tuning the ring, the device achieves a rapid roll-off on the band edges, a wide 3-dB bandwidth of 0.95 nm and a low crosstalk of 14 dB. The filter can be used in the WDM network and integrated microwave photonic signal processing.
