Mid-infrared generation beyond 3.5 µm in a graded-index silica fiber [PDF]
EPJ Web of Conferences, 2023 We present theoretical as well as experimental evidence of far-detuned nonlinear wavelength conversion towards the mid-infrared, namely beyond 3.5 µm, in a few-mode graded-index silica fiber pumped at 1.064 µm.

Measurement of Principal Modes in Few-Mode Fibers by S2 Method
IEEE Photonics Journal, 2020 Using principal modes (PMs) can avoid the inter-mode crosstalk in fiber-optic communication and reduce the complexity of digital signal processing. In this paper, a new detection method for PMs based on spatially and spectrally resolved imaging (S2) is ...

Mode division multiplexing using an orbital angular momentum mode sorter and MIMO-DSP over a graded-index few-mode optical fibre [PDF]
, 2015 Mode division multiplexing (MDM)– using a multimode optical fiber’s N spatial modes as data channels to transmit N independent data streams – has received interest as it can potentially increase optical fiber data transmission capacity N-times with ...

Measuring Distributed Mode Scattering in Long, Few-Moded Fibers [PDF]
Optical Fiber Communication Conference, 2012 We present measurements of higher-order modes in lengths of few-moded fibers up to 0.5 km long using Spatially and Spectrally resolved (S2) imaging. Both discrete scattering events and mode-mixing due to distributed scattering are measured.

Enhancement of modal stability through reduced mode coupling in a few-mode fiber for mode division multiplexing [PDF]
, 2018 We demonstrate a novel approach to enhance the modal stability between the modes of a few-mode fiber (FMF) by increasing the effective index differences between these modes.

IEEE Photonics Journal, 2023 The mode field distribution at the distal end of a multimode fiber can vary randomly when environmental perturbations introduce changes in the relative phases of different eigenmodes and variations in coupling among modes.

Mode and Wavelength-Switchable Pulsed Fiber Laser With Few-Mode Fiber Grating [PDF]
IEEE Photonics Technology Letters, 2019 We propose and demonstrate a mode and wavelength-switchable pulsed fiber laser using two-mode fiber Bragg grating (TM-FBG) as both transverse mode converter and wavelength selector. The mode-locking mechanism is based on saturable absorption of semiconductor saturable absorption mirror (SESAM).
