## Abstract New structures that can realize single and triple output coherence‐free microwave photonic filter are presented. They are based on a Sagnac loop interferometer containing a single drive intensity modulator and a 3 × 3 collinear coupler, and no non‐reciprocal bias unit is required. Notch
