Multimode interference couplers (MMIs) are fundamental building blocks in photonic
integrated circuits. Here it is experimentally demonstrated, for the first time, a two‐fold length …

We propose an ultra-broadband multimode interference (MMI) coupler with a wavelength
range exceeding the O, E, S, C, L and U optical communication bands. For the first time, the …

We demonstrate a compact () four-channel wavelength division multiplexer using an arrayed
waveguide grating based on multimode interference couplers, and built on a monolithic …

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 …

We demonstrate compact multimode interference (MMI) couplers on silicon-on-insulator that
exhibit both high performance and relaxed tolerances. The devices are fabricated with a …

The performance of multimode interference (MMI) couplers in silicon waveguides is limited
by the high lateral refractive index contrast. Here we propose the use of subwavelength …

Parasitic reflections can deteriorate the performance of a photonic integrated circuit. This is
especially true in circuits containing amplifiers, but even in passive circuits, small reflections …

A silicon triplexer based on Bragg grating-assisted multimode interference (MMI) couplers is
designed and experimentally demonstrated. Compared with the conventional MMI-based …

A library of compact multimode interference (MMI) couplers with MMI region widths ranging
from 1.1 μm to 3.2 μm is presented for 220-nm silicon-on-insulator-based photonic circuits …

We show that it is possible to obtain 2?? 2 waveguide couplers with arbitrary power splitting
ratios by interconnecting a pair of unequalwidth waveguides as the phase-tuning section …
