Abstract: Long-distance distributed fiber-optic sensing based on optical pulse coding is widely applied in structural health monitoring and geological disaster early warning. However, erbium-doped ...
An Osaka Metropolitan University-led research team investigated the decay time of coherent longitudinal optical (LO) phonons both in a GaAs 1−x N x epilayer and in a GaAs single crystal, to clarify ...
Phlux Technology, a manufacturer of avalanche photodiode infrared sensors, will exhibit its Aura family of Noiseless InGaAs APDs at SPIE Photonics West, San Francisco, January 20-22, 2026. The company ...
ABSTRACT: With super high-rise buildings developing towards characteristics of low damping, light weight, and high flexibility, their wind-induced vibration and aeroelastic effects have become key ...
As fibre optic networks grow in both size and complexity, so does the need to monitor their performance in real time. The Optical Time Domain Reflectometer (OTDR) is a familiar instrument used by ...
Abstract: Global telecommunications heavily rely on optical fibers as the foundation of their network infrastructure, making it imperative for network operators to ensure their dependability. The ...
