Reduced coating diameter fibers (RCDF) are attractive for increasing fiber density in cables due to their compatibility with the standard 125 μm clad diameter. In this paper, we review recent prog…
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…
We designed and fabricated a ring-core Bi/Er co-doped fiber (RC-BEDF), and thus investigated the broad-spectrum amplification of orbital angular momentum (OAM) modes. The deviation from the average…
Polarization devices on lithium niobate thin film (LNTF) are vital components for photonic integrated circuits (PICs) on the novel platform. Because both linear and nonlinear devices on the anisotr…
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…
Thermo-optic phase-shifter is an important component widely used in various photonic applications such as optical neural network and LiDAR. Different methods have been proposed to improve the perfo…
The filtering parameters of non-local means (NLM) that seriously affect the denoising results are usually optimized based on the noise level estimation. But the noise level is unknown in many cases…
We present a high-power, polarization-maintaining (PM) Er 3+ -doped fluoride fiber amplifier, which enables watt- level, linearly-polarized (LP) superfluorescent outputs around 2.8 μm by using a n…
Facial expression recognition (FER) has received significant attention in the past decade with witnessed progress, but data inconsistencies among different FER datasets greatly hinder the generaliz…
