Abstract:
For multi-mode interference (MMI) couplers that have a plurality of input and output ports, e.g. 4×4, a large number of modes may be supported in the multimode region, e.g. >10, as the width of the MMI core grows larger. In order for MMI couplers to form good images, the supported modes preferably have low modal phase error, which can't be achieved using a conventional single layer design. Accordingly, a multi-mode interference (MMI) coupler comprising an MMI core comprising a plurality of waveguide core strips alternating with a plurality of cladding strips solves the aforementioned problems.

Claim (Index 34):
The coupler according to  claim 33 , further comprising:\n a fifth waveguide comprising a third output waveguide section extending from the other side of the coupler, and a third expanding section adjacent to the second tapering section, the third expanding section expanding as the second tapering section tapers;
