Text encoding is one of the most important steps in Natural Language Processing (NLP). It has been done well by the self-attention mechanism in the current state-of-the-art Transformer encoder, whi…
Distributed acoustic sensing is a recently developed technique that has demonstrated its utility in vibration and strain detection. However, for conventional demodulating algorithm, the dynamic ran…
In this paper, multi-dimensional distribution matching (MDDM) based on bit-level shaping is proposed to implement probabilistic shaping (PS) for high order modulation formats. MDDM is optimized acr…
Recently, end-to-end deep learning (E2EDL) has been proposed for communication systems to improve the overall performance of systems. In the domain of optical fiber communication systems, the theor…
In this paper, we proposed an improved mobile fronthaul architecture employing the SNR-improved delta-sigma digitization scheme and 4-level pulse amplitude modulation (PAM-4) format. Different from…
An accurate quality of transmission (QoT) estimation can help to reduce the design margin of optical network planning. The physical layer impairments (PLI) modeling can be the basis of QoT estimati…
The photosensitive behaviors in laser grating formation is an important guideline for the preparation of drawing tower gratings (DTGs) in different optical fibers. We conducted static single-pulse …
We firstly propose a roadmap for thedesign of high repetition rate (∼100 MHz) Tm-doped ultrafast fiber laser with an emission wavelength above 2000 nm. This roadmap is confirmed by both theoretic…
The key idea of this work is to treat the symbol- pattern-dependent inter-symbol-interference (ISI) that is avoided in conventional single-symbol modulation systems as useful symbol correlation, in…
