Time-Varying Optical Spin-Orbit Interactions in Tight Focusing of Self-Torque…
Self-torque has recently been observed as a novel property of light that features time-varying orbital angular momentum (OAM) along a light pulse. This property offers an additional degree of freed…
Singularity Reconfiguration of Non-Diffraction Structured Light
It's a basic characteristic that there exists a phase singularity located at the center for pure vortex light. If combining several vortex lights belonging to the same eigenmode set, the central hi…
108.96 nm Broadband Generation of Second-Order OAM Beam Using an Angular Modu…
Broadband generation of orbital angular momentum (OAM) beam in fiber has a lot of applications in optical communications and fiber sensing. However, the efficient broadband generation of second-ord…
Non-Zero Dispersion-Shifted Ring-Core Fiber Supporting 60 OAM Modes
Orbital angular momentum (OAM) modes have becoming more promising to further achieve higher spectral efficiency and data capacity in space-division-multiplexing (SDM) fiber communication systems. I…
Dual Concentric-Ring-Core Fiber With Four Zero-Dispersion Wavelengths for Bey…
Orbital angular momentum (OAM) beams, featuring with unique spatial field distributions, have been extensively investigated and applied into a wide range of fields. In most applications, OAM beams …
Risk-Based Robust Statistical Learning by Stochastic Difference-of-Convex Val…
This paper proposes the use of a variant of the conditional value-at-risk (CVaR) risk measure, called the interval conditional value-at-risk (In-CVaR), for the treatment of outliers in statistical …
Characterization and Manipulation of Temporal Structures of Dispersive Waves …
Dispersive waves (DWs) are ubiquitous in nonlinear optical systems that host optical solitons. In particular, DWs in soliton fiber lasers have attracted continuous interest over the past decades si…
Synchronization of Two Microwave Sources With Femtosecond-level Residual Timi…
A microwave photonic phase detector (MPPD) for simultaneous synchronization of two independent microwave sources to a single mode-locked laser (MLL) with femtosecond-level residual timing jitters i…
Immunity to Mutual Interference in Coded Phase-Shift LiDAR
When the light detection and ranging (LiDAR) scans a space, the echo signal affected by diffuse reflections may be captured by other LiDAR detectors to interfere with their echoes. The ghost points…
Long Distance Distributed Strain Sensing in OFDR by BM3D-SAPCA Image Denoising
We present a long distance distributed strain sensing in optical frequency domain reflectometry (OFDR) by shape-adaptive principal component analysis Block-Matching three-dimensional filter (BM3D-S…
