RING RESONATOR INCLUDING NESTED MACH ZEHNDER MODULE

摘要

An optical filter includes at least one ring resonator (28) that receives as input an optical signal having a plurality of channels from an input optical source. At least one Mach-Zehnder module (26) is nested in the at least one ring resonator (28). The at least one Mach-Zehnder module and the at least one ring resonator filter at least one selective channel from the optical signal.
