Structured light, also known as tailored light, shaped light, sculpted light, or custom light,
refers to a series of special light beams with spatially variant amplitudes and phases …

We present an ultra-broadband and low-modal-crosstalk mode multiplexer based on
cascaded vertical directional couplers formed by adiabatic-tapered waveguides without …

Transmission based on mode-division multiplexing can enhance node flexibility in
metropolitan networks by exploiting mode-group routing. In fact, each mode group …

Diverse spatial mode bases can be exploited in mode-division multiplexing (MDM) to
sustain the capacity growth in fiber-optic communications, such as linearly polarized (LP) …

In this article, a novel Bayes-Adam-based multiple-input multiple-output (MIMO) equalizer
was proposed and experimentally demonstrated for an orbital angular momentum (OAM) …

摘要基于模式/模群复用的多模光纤通信系统是目前光通信领域的研究热点.
系统中存在多个模式/模群, 如何准确识别它们是提升传输系统性能的关键问题之一 …

The choice of linear polarization modes in optical fiber is a key factor affecting performance
of mode division multiplexing system (MDM). Firstly, an intensity modulation and direct …

We demonstrate a class of all-fiber torsion-tunable orbital angular momentum (OAM) mode
generators based on oxyhydrogen-flame fabricated helical long-period fiber gratings …

We propose a digital-carrier Kramers–Kronig (DC-KK) scheme based high-speed multimode
fiber short-reach optical interconnect system with fundamental mode transmission. After …

As optical networks urgently seek for extra capacity, Space Division Multiplexing (SDM)
seems to be able to provide it. SDM can deploy multiple spatial channels in multi-core …
