    We experimentally study the modal interactions in mode division multiplexing (MDM) links supporting orbital angular momentum (OAM) modes of order zero and one. We use time of flight and channel impulse response measurements to characterize our OAM-MDM link and quantify ...

    We demonstrate MIMO-free two-dimensional multiplexing, transmission and de-multiplexing over 4 OAM modes (including two modes of |l| = 2) and 15 wavelengths through 100-meter inverse-parabolic graded-index fiber with aggregated total capacity of 3.36-Tbit/s.

    We present an analytical and numerical description of coupling between OAM modes in hollow ring-core fibers affected by stress birefringence and ellipticity. The analysis paves the way to a better modeling of propagation in these fibers.

    We characterize an OAM-MDM link by measuring the channel impulse response using two OAM fiber designs investigating the impact of TE 01 , TM 01 modes on receiver performance and required equalizer taps in separate mode detection schemes.

    Mode division multiplexing (MDM) systems using orbital angular momentum (OAM) modes can recover the data in D different modes without recourse to full (2 D × 2 D ) multiple input multiple output (MIMO) processing. One of the biggest challenges in OAM-MDM systems is the ...

    The effect of spin-orbit coupling in air-core optical fibers degrades the purity of orbital angular momentum modes and induces significant crosstalk. We numerically investigate different air-core fiber geometries and discuss the trade-off between OAM mode purity and eff...

    The orbital-angular-momentum (OAM) modes in optical fibers have polarization mode dispersion (PMD) properties similar to those of single-mode fibers (SMFs). The + l and − l order OAM modes supported by the same fiber vector modes undergo random cross coupling and exhibi...

    The ROAM (Revolutionizing optical fiber transmission and networking using the Orbital Angular Momentum of light) project investigates the orbital angular momentum (OAM) modes of light for communications and networking applications. OAM modes are exploited as a disruptiv...

    Novel optical fiber designs are currently investigated to enable optical communication links with higher capacity and bandwidth density. In this paper, we discuss the prospects and challenges of ring core fibers for MIMO-free transmissions over multiplexed spatial chann...

    The orbital-angular-momentum states in fibers have similar polarization-mode dispersion property than single mode fibers. A fixed-analyzer technique is demonstrated to characterize this phenomenon in an OAM fiber that supports up to the second order OAM mode.
