Abstract: A notch filter circuit includes a wavelength demultiplexer, a first pump rejection filter coupled to the wavelength demultiplexer, and a second pump rejection filter coupled to the wavelength demultiplexer. The notch filter circuit also includes a first notch filter arm coupled to the first pump rejection filter and including a first chain of asymmetric Mach-Zehnder interferometers (MZIs) and a second notch filter arm coupled to the second pump rejection filter and including a second chain of asymmetric MZIs.
