摘要:Abstract(#br)Alzheimer's disease (AD) is a chronic neurodegenerative disease. The genetic risk factors of AD remain better understood. Using previously published dataset of common single nucleotide polymorphisms (SNPs), we studied the association between the minor allele content ...

摘要:Abstract(#br)In this paper, we propose and demonstrate a prototype of millimeter-wave (MMW) generator with tunable multiplication factors. A dual-parallel Mach-Zehnder modulator and a remodulation structure are used to effectively excite higher-order optical sidebands and a progr...

摘要:Abstract(#br)In this study, we propose and demonstrate a prototype for optically generating millimeter-wave (MMW) signals with tunable multiplication factors and reduced power fluctuation. The proposed scheme is based on two Mach-Zehnder modulators (MZM) and a polarization c...

摘要:Abstract(#br)In this study, two filterless frequency-tupling millimeter-wave (mm-wave) generator schemes are theoretically analyzed and verified by simulation. The first one is a frequency 12-tupler, made by a dual-parallel Mach–Zehnder modulator (DP-MZM), capable of generat...

摘要:Abstract(#br)A fiber optic sensor capable of measuring strain and temperature simultaneously is proposed and demonstrated. The key component is a no-core fiber (NCF) followed by a fiber Bragg grating (FBG), which helps to resolve the crosstalk issue. The interference fringe ...

摘要:Abstract(#br)We propose a photonic-assisted triangular-shaped pulse train generator based on four-wave mixing effect (FWM) in a semiconductor optical amplifier (SOA). A dual-parallel Mach–Zehnder operated at quadrupling RF modulation is employed to generate two primary sideb...

摘要:Abstract(#br)A novel approach to the optoelectronic oscillator (OEO) for the generation of a microwave signal with simultaneously frequency and phase tunability is proposed and experimentally demonstrated. In the proposed OEO, a carrier phase-shifted double-sideband modulate...

摘要:Abstract(#br)A photonic triangular-shaped pulse train is generated based on optical subcarrier modulation and harmonic fitting. After modulated by an amplitude modulator, a single symmetrical triangle-shaped pulse is extracted to investigate the optical wavelength conversion caus...

摘要:Abstract(#br)A tunable optical frequency comb generator (OFCG) by cascading an Electro-absorption modulator (EAM) followed by a phase modulator (PM) and an intensity modulator (IM) is proposed for wavelength division multiplexing radio-over-fiber (WDM-RoF) transmission. The ...
