In optical fiber, the Orbital Angular Momentum (OAM) mode is a special mode with spatially
infinite orthogonality. It provides a new multiplexing method to the communication capacity …

We experimentally demonstrated a high-order optical vortex pulsed laser based on a mode
selective all-fiber fused coupler composed of a single-mode fiber (SMF) and a few-mode …

Orbital angular momentum beam excitation through direct phase-matched coupling is
experimentally demonstrated using an all-fiber weakly fused mode selective coupler …

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 …

We propose an effective approach to generate tunable orbital angular momentum (OAM)
beam based on all-fiber fused coupler consisting of a single mode fiber (SMF) and a two …

The stable generation of TE 01 and TM 01 beams is demonstrated through a novel all-fiber
fused coupler fabricated from a standard single mode fiber (SMF) and a custom air-core …

We propose and demonstrate an all-fiber laser with LP_11 mode output. A transverse mode
filter is designed and fabricated to suppress the fundamental mode and enable the fiber …

We experimentally demonstrate a switchable narrow linewidth single-longitudinal-mode
(SLM) erbium-doped fiber (EDF) ring laser with LP 11 transverse mode output. The laser is …

We propose orbital angular momentum (OAM) mode generation using an all-fiber coupler
based on hollow-core circular photonic crystal fibers (PCF). Using the mode-matching …

We propose and design a new kind of all-fiber polarization beam splitter and rotator (PBS
and PBR) based on vector-mode-assisted coupling. By embedding a high-contrast-index …
