High-Precision Mode Decomposition for Few-Mode Fibers Based on Multi-Task Dee…

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…

Laser Performance of Active Segment Cladding Fiber Under Heat Load

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…

All-Optical Graphene Oxide Modulator Based on Phase-Shifted FBG

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…

Optical Spectral Slicing Based Reconfigurable and Tunable Microwave Photonic …

Multiband microwave photonic filters (MPFs) are extensively required in emerging multifunction RF systems and high-performance radar systems. In this article, we present a reconfigurable and tunabl…

Switchable, Widely Tunable and Interval-Adjustable Multi-Wavelength Erbium-Do…

A novel individually switchable, widely tunable, and interval-adjustable multi-wavelength erbium-doped fiber laser (EDFL) is experimentally demonstrated in this article. It is based on the cascaded…

Measurement of Instantaneous Microwave Frequency by Optical Power Monitoring …

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…
