Mode-division multiplexing (MDM) technology has drawn tremendous attention for its ability
to expand the link capacity within a single-wavelength carrier, paving the way for large-scale …

Multimode devices and components have attracted considerable attention in the last years,
and different research topics and themes have emerged very recently. The multimodality can …

As a fundamental building block for photonic integrated circuits, waveguide crossing is
playing an essential role for routing the increasingly complex network on chip. Driven by the …

To overcome the capacity crunch of optical communications based on the traditional single-
mode fiber (SMF), different modes in a few-mode fiber (FMF) can be employed for mode …

In this paper, we design and experimentally demonstrate a two-mode and three-mode mode
exchanger (ME) using an inverse design method. The designed MEs provide more flexibility …

Reconfigurable mode converters are essential components in efficient higher-order mode
sources for on-chip multimode applications. We propose an on-chip reconfigurable silicon …

Guided wave optics, including most prominently fiber optics and integrated photonics, very
often considers only one or very few spatial modes of the waveguides. Despite being known …

Silicon-based optical switches are integral to on-chip optical interconnects, and mode-
division multiplexing (MDM) technology has enabled modes to function as carriers in …

Optical power splitters are fundamental devices in on-chip optical systems, enabling
coherent optical modulation through beam splitting and combining. Despite many mature …
