Beam splitters are core components of photonic integrated circuits and are often
implemented with multimode interference couplers. While these devices offer high …

We report multimode-interference (MMI)-based crossings in high-index-contrast silicon wire
waveguides. Our experiments show an MMI crossing of~ 0.4-dB insertion loss, which …

We present the design, fabrication and characterization of a highly efficient silicon
waveguide crossing based on multimode interference (MMI). The crossing is formed by only …

An improved approach for optimization of N× N silica multimode interference (MMI) couplers
is presented in this paper. Using guided-mode propagation analysis, we adjust the width …

A dual-mode waveguide crossing is proposed and realized for the application of on-chip
multimode interconnection. The present structure is realized by two 90° crossed multimode …

Optical splitters and combiners which can provide precise splitting with low loss, high
thermal stability, large optical bandwidth, high compactness, and insensitivity to fabrication …

Based on restricted interferences mechanism in a 1x2 MMI beam splitter, we theoretically
investigate and experimentally demonstrate an ultra-compact MMI-based demultiplexer for …

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 …

Today, photonic integrated circuits (PIC) that work with a high-modulation speed (100Gb/s
and beyond) are required to use more optical power to overcome the losses. One solution is …

We propose a novel optical 1× 2 power splitter based on an asymmetric ladder-shaped
multimode interference (MMI) coupler in silicon-on-insulator (SOI) which has an ultra …
