We propose and demonstrate an ultra-broadband mode converter based on a cascade
chirped long-period fiber grating (CLPFG) written in a two-mode fiber. The mode converter …

We propose an ultra-broadband mode converter based on the structure of a length-
apodized long-period grating, where π-phase shifts are introduced at strategic locations of …

We present a study of simultaneous detection of curvature and strain in optical fiber. This
contains a micro tapered section and a nano tapered section. The transmission spectrum …

In this work, a higher order-to-fundamental mode converter is reported and analyzed based
on an asymmetric dual channel waveguide (ADC-WG) on silicon. In the reported structure …

A compact tunable mode converter device based on the thermo-optically characteristics of
liquid crystals (LCs) is proposed and numerically analyzed herein. The proposed mode …

In this study, a compact mode converter based on an asymmetric dual-core photonic crystal
fiber (ADC-PCF) infiltrated with nematic liquid crystal (NLC) is reported. The full vectorial …

We propose a novel mode selective directional coupler based on microstructured cane for
higher order modes excitation. The coupler is composed by a single mode fiber (SMF) and a …

In wireless laser communication systems, owing to the influence of atmospheric turbulence
on the spatial-light mode, the beam mode degrades, which leads to incomplete matching …

We propose a new asymmetric directional coupler including two different fibers for LP 01
mode excitation. Two methods are presented to selectively excite the LP 01 mode in a few …

We propose to connect a single-mode fiber (SMF) to a dual-concentric cores fiber (DCCF)
using an adiabatically tapered microstructured mode converter, and to evaluate the SMF LP …
