Multimode silicon photonics is attracting more and more attention because the introduction
of higher-order modes makes it possible to increase the channel number for data …

On-chip mode-manipulation is one of the most important physical fundamentals for many
photonic integrated devices and circuits. In the past years, great progresses have been …

A low-loss and low-crosstalk multimode waveguide bend is proposed and demonstrated for
mode-division-multiplexed optical interconnects. The proposed 90°-bend is composed of …

We review the current status of mode-division multiplexing (MDM) techniques in fibers and
on chips. Three system applications are introduced, including quasi-single mode …

Mode-division multiplexing (MDM) can greatly improve the capacity of information
transmission. The multimode waveguide bend (MWB) with small size and high performance …

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 …

Countless waveguides have been designed based on four basic bends: circular bend,
sine/cosine bend, Euler bend (developed in 1744) and Bezier bend (developed in 1962) …

Waveguide superlattices with a subwavelength pitch and low crosstalk can significantly
increase the waveguide integration density and are beneficial for many chip-scale …

We experimentally demonstrate wavelength-independent couplers (WICs) based on an
asymmetric Mach-Zehnder interferometer (MZI) on a monolithic silicon-photonics platform in …

Mode-division multiplexing (MDM) is an effective solution to extend the capacity of optical
communication system. Multimode waveguide bend (MWB), one of the key components, is …
