Refractive index profile (RIP) determines the property and effectiveness of optical fibers. Accurate measurement of the RIP is essential for fiber fabrication, test and calibration. At present, com…
A novel mode decomposition (MD) method based on multi-task learning (MTL) is proposed to obtain high-precision modal weights ( ρn2 ) and modal relative phases ( θn ). Due to the different physica…
System stability and robustness are highly desired in a mode division multiplexing (MDM) transmission system. The matching of the active fiber and transmission FMF effectively reduces the transmiss…
Methodologies for functional principal component analysis are well established in the one-dimensional setting. However, for two-dimensional surfaces, for example, images, conducting functional prin…
An amplifier model based on the Yb-doped segment cladding fiber (SCF) is proposed in this paper. Three contributions to heat source are taken into account in the proposed model, including the quant…
An all-optical graphene oxide modulator based on phase-shifted FBG is proposed and experimentally proved to overcome the electronic bottleneck. The phase-shifted FBG is formed by tapering and the s…
A photonic-assisted approach for instantaneous frequency measurement based on optical power monitoring is proposed and demonstrated. Instead of using optical filter, a dual-polarization Mach-Zehnde…
