The compensation for in-phase/quadrature (IQ) and polarization imbalance residing at the coherent transceivers is crucial to the overall performance of high-speed transmission systems. To simultane…
Within a context of C+L band transmission, this work proposes a design approach for Raman pumps in hybrid fiber amplifiers (HFAs) with the goal of maximizing the total system capacity. First, the o…
In this paper, we propose to reduce the size of look-up table (LUT) for digital pre-distortion in optical communication using principal component analysis (PCA). In this scheme, the full-size LUT a…
Phase retrieval (PR) schemes based on modified Gerchberg-Saxton (GS) algorithm using pilot symbol or pilot tone have recently attracted great attentions in self-coherent systems. In this work, we p…
High-power narrow-linewidth continuous fiber lasers have wide applications in the fields of power synthesis, nonlinear frequency conversion, and industrial processing. The output power of kW or eve…
Blue LEDs are cost-effective optical sources suitable for underwater optical wireless communication (UOWC) systems. However, the nonlinearity and the low-pass response of LEDs alongside the limited…
Machine learning (ML) has been widely used for physical layer modeling in optical networks for its high accuracy and efficient calculation structure. However, traditional ML-based methods purely re…
Standard coherent communication technology is being introduced to short-reach optical communications to further scale the link throughput by leveraging more degrees of freedom of an optical channel…
Dual-comb source (DCS) generation occupies the central position to the versatilities of dual-comb applications. The single-cavity-based DCS generation is an emerging technology which provides super…
Optical full-field recovery allows for fiber impairments compensation such as chromatic dispersion and polarization mode dispersion (PMD) in the digital signal processing. For cost-sensitive short-…
