In this paper, an encrypted three-dimensional (3D) trellis-coded modulation (TCM) based on mapping by set-partitioning (MSP) of 3D constellation is proposed, for highly reliable and secure short-re…
In this paper, a power sparse code division non-orthogonal multiple access (PSCD-NOMA) scheme is proposed for next-generation flexible optical access, which is based on the multi-stack network. All…
In this paper, we propose a novel optical non-orthogonal multiple access (NOMA) scheme based on orthogonal chirp division multiplexing (OCDM) in a low-cost intensity modulation and direct detection…
In this paper, we establish a modified equivalent circuit model suitable for all bias conditions for high-speed InGaAs/InAlAs avalanche photodiodes (APDs). The model includes three mechanisms: the …
A novel fast-response sensitivity-enhanced high-temperature all-fiber Fabry–Pérot high-pressure sensor formed with a hard-core diaphragm is proposed and demonstrated. The structure can effective…
The human brain is a directional network system of brain regions involving directional connectivity. Seizures are a directional network phenomenon as abnormal neuronal activities start from a seizu…
The proliferation of social media platforms allows marketers to gauge consumers’ opinions toward brands directly from online word of mouth (WOM). In this paper, we exploit a large-scale televisio…
Dual-wavelength mode-locked fiber lasers are considered as ideal solutions for fast, precise, and sensitive dual-comb spectroscopy. In this study, we present a self-started dual-wavelength fiber la…
The optical wireless communication (OWC) system has been widely studied as a promising candidate for indoor high-speed wireless communications. In particular, the spatial diversity scheme has shown…
We propose two types of temperature-compensated all-fiber sensors based on a novel laser-machined Fabry-Perot interferometer (FPI) whose sensitivity is adjusted by controlling the FPI gauge length …
