Abstract
New structures that can realize dual and triple output coherent-free bandpass microwave photonic filter are presented. They
are based on a Sagnac loop interferometer containing a phase modulator, a 3×3 collinear coupler and without nonreciprocal
bias unit. Measured results demonstrate robust notch filter responses for DFB laser source or broadband source.
