All-PM fiber supercontinuum source with 30.8W output average power and spectral span from 430 nm to beyond 2400nm

Tianjiao Wang, Tianshu Wang, Bo Zhang, S.D. Liu et autres

This work reports the generation of a linearly polarized supercontinuum (SC) using an all-polarization-maintaining master-oscillator power-amplifier (MOPA) pumping a polarization-maintaining photonic crystal fiber (PM-PCF). The source delivers an average output power of 30.8 W and, after removing the residual pump, provides a …

Path Planning of a New Undersea Telecommunications Cable with Consideration of Crossing Angle with Existing Cables

Xinyu Wang, Fahan Chen, Zengfu Wang, Tianjiao Wang et autres

Undersea telecommunication cables are critical components of the global infrastructure, with nearly every coastal nation connected via these "seabed highways." As of early 2025, there are over 600 active and planned undersea cables worldwide, spanning approximately 1.48 million kilometers and transmitting 99% …

Time-Harmonic Elastic Scattering by Unbounded Deterministic and Random Rough Surfaces in Three Dimensions

Guanghui Hu, Tianjiao Wang, Xiang Xu, Yue Zhao

Abstract. In this paper, we investigate well-posedness of time-harmonic scattering of elastic waves by unbounded rigid rough surfaces in three dimensions. Both deterministic and random surfaces are investigated through the variational approach. In a deterministic setting, the rough surface is assumed to …

Evaluating and refining undersea cable path planning algorithms: A comparative study

Tianjiao Wang, Zengfu Wang, Bill Moran, Xinyu Wang et autres

This paper compares three automated path-planning algorithms based on publicly available data. The algorithms include a Dijkstra-based algorithm (DBA) that improves on the straightforward application of Dijkstra's algorithm, which restricts the path only to the grid edges. We present a fair and …

Time-harmonic elastic scattering by unbounded deterministic and random rough surfaces in three dimensions

Guanghui Hu, Tianjiao Wang, Xiang Xu, Yue Zhao

In this paper, we investigate well-posedness of time-harmonic scattering of elastic waves by unbounded rigid rough surfaces in three dimensions. The elastic scattering is caused by an $L^2$ function with a compact support in the $x_3$-direction, and both deterministic and random surfaces …

Capacity-Aware Undersea Cable System Design

Tianjiao Wang, Bill Moran, Moshe Zukerman

Undersea cables play a crucial role in enabling global communication and data transfer, significantly affecting Internet speeds. Without them, global communication would be severely limited. As technology advances and network demands increase, the number and variety of optical fibers within cables are …
