During the last decade, optical networks have become “smart networks”. Software-defined
networks, software-defined optical networks, and elastic optical networks are some …

Future communication systems are faced with increased demand for high capacity, dynamic
bandwidth, reliability and heterogeneous traffic. To meet these requirements, networks have …

The problem of automatic modulation format identification (MFI) is one of the main
challenges in adaptive optical systems. In this work, we investigate MFI in super-channel …

Few-mode fiber (FMF), a mode multiplex technique, has been a candidate to provide high
transmission capability in next-generation elastic optical networks (EONs), where the …

We propose and demonstrate an optical performance monitoring (OPM) scheme in few-
mode fiber (FMF) based elastic optical networks (EONs). In this work, an adversarial transfer …

Abstract Inter-symbol interference (ISI), mode coupling (MC) and other impairments present
in high baud rate mode division multiplexing (MDM) systems significantly degrade the …

We thoughtfully investigate the feasibility of reducing the mode-coupling caused crosstalk by
optimizing the practical parameters of the few-mode fiber (FMF), based on the linear …

Due to their greatly increased spectrum efficiency, high-order quadrature amplitude
modulation (QAM) formats are especially successful at increasing transmission capacity …

We propose and experimentally demonstrate a microwave frequency measurement system
based on the photonic technique. An amplitude comparison function is constructed to …

In this paper, we propose a multi-feature fusion network (MFF-Net) for a modulation format
identification (MFI) and optical signal-to-noise ratio (OSNR) monitoring scheme. The …
