Structured light beams have rapidly advanced over the past few years, from specific spatial-
transverse/longitudinal structure to tailored spatiotemporal structure. Such beams with …

Optical orbital angular momentum (OAM) has become a hot research topic because of its
unique properties due to its spiral distribution of phases. The production and transmission of …

Orbital angular momentum (OAM) of light beams with helical phase front, as an alternative
spatial dimension resource of photons, has attracted extensive attention over the past …

X-ray beams carrying orbital angular momentum (OAM) are an emerging tool for probing
matter. Optical elements, such as spiral phase plates and zone plates, have been widely …

A weakly-coupled few mode fiber (FMF) with a simple double-layer core is designed and
fabricated that support five (seven) weakly coupled mode groups with average attenuation of …

With the rapid development of optical fiber sensor in physical measurement, it is of practical
significant to realize multi-parameter measurement. In this work, we proposed and …

In this paper, we propose and design a multi-orbital-angular-momentum multi-ring air-core
fiber, which has seven high-index rings with each ring supporting 62 radially fundamental …

The linear polarized (LP) mode multiplexer based on the inverse designed multi-plane light
conversion (MPLC) has the advantages of low insertion loss and low mode crosstalk …

Diverse spatial mode bases can be exploited in mode-division multiplexing (MDM) to
sustain the capacity growth in fiber-optic communications, such as linearly polarized (LP) …

Orbital angular momentum (OAM) multiplexing technology is expected as one of the
prospective candidates for sustaining the further increment of data-transmission capacity in …
