A compact multimode interference (MMI) coupler is realized by using deeply-etched SiO2
ridge waveguides, which have a strong confinement in the lateral direction and improve the …

We show that the weighted sum of phase errors of modes of multimode interference (MMI)
waveguide is minimum for largest access waveguide width. Also, we show the improvement …

We derived an analytical formula for the optimum width of the access waveguides of 1× N
multimode interference (MMI) couplers. Eigenmode-decomposition-based simulations show …

A new tapered structure based on general interference has been proposed and realized by
using silica waveguides with a silicon oxinitride (SiON) core for the reduction of coupling …

theoretically with silica waveguides of silicon oxinitride (SiON) core by using a mathematical …

The authors propose a novel 2× 2 multimode interference (MMI) coupler that provides an
arbitrary power splitting ratio. The proposed coupler has a cladding-filled gap in the centre of …

The design and fabrication of a 4× 4 multimode interference (MMI) coupler is reported. A
photopatternable organic-inorganic sol-gel on silica-on-silicon is adopted for the device …
