Experimental confirmation of phase relationships of multimode interference splitters using a shearing-type near-field Sagnac interferometer

We report, for the first time, the experimental confirmation of the phase relationships between the output images of 1/spl times/4 and 1/spl times/8 multimode interference (MMI) splitters. Interference data is obtained using a shearing type near-field Sagnac interferometer. A Fourier transform techn...
