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…
Offline and Online Objective Reduction via Gaussian Mixture Model Clustering
The objective reduction has been regarded as a basic issue in many-objective optimization. Existing objective reduction methods identify one set of essential objectives using an approximate nondomi…
Bandwidth Characteristics of Mid-Wavelength Infrared PIN HgCdTe Avalanche Pho…
HgCdTe avalanche photodiodes (APDs) are used in mid-wavelength infrared (MWIR) photoelectric detectors in free-space optical communication, three-dimensional light detection, and ranging. Although …
Ultrahigh Efficiency Four-Wave Mixing Wavelength Conversion in Packaged Silic…
Whispering-gallery-mode (WGM) resonator with high-quality factor ( Q ) is a key platform for a wide range of fields including nonlinear optics, biosensing and quantum photonics. In this work, a pac…
Secure Encryption and Key Management for OFDM-PON Based on Chaotic Hilbert Mo…
We propose a novel security enhancement technique for physical layer secure orthogonal frequency division multiplexed-based passive optical network (OFDM-PON) using chaotic Hilbert motion. By using…
All-Polarization-Maintaining Figure-9 Mode-Locked Tm-Doped Fiber Laser With A…
An all-polarization-maintaining (PM) figure-9 mode-locked Tm-doped fiber laser that leverages a nonlinear amplifying loop mirror (NALM) incorporated with a chirped fiber Bragg grating (CFBG) for di…
Theoretical Analysis of the Mode Distortion Induced by Stimulated Raman Scatt…
By employing the mode decomposition method to study the relative mode evolution characteristics during the stimulated Raman scattering (SRS) process, a numerical model of the core-pumped Raman effe…
3 μm Watt-Level All-Fiber Lasers Based on Mid-IR Dielectric-Coated Fiber Mir…
We report watt-level mid-IR Dy 3+ - and Er 3+ -doped all-fiber lasers using highly resistant dielectric-coated fiber mirrors. The fiber pigtail mirror is specifically designed for dichroic operatio…
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…
Elimination of Side Lobe Ghost Peak Using Wiener Deconvolution Filter in OFDR
Ghost peaks refer to these peaks on backscattering trace measured by a reflectometer similar to Fresnel reflection peaks appearing at the position of non-reflection events in optical fiber or optic…
