The Periodic Gaussian Process (PGP) has been increasingly used to model periodic data due to its high accuracy. Yet, computing the likelihood of PGP has a high computational complexity of O(n3) (n …
We present a Bayesian nonparametric model for conditional distribution estimation using Bayesian additive regression trees (BART). The generative model we use is based on rejection sampling from a …
This paper extends a recent demonstration of a 2-line side 15-mode spatial division multiplexing network node. The node is based on fifteen 2 × 2 wavelength cross-connects (WXCs) to direct up to s…
A photonic-assisted scheme is proposed and demonstrated for microwave frequency down-conversion based on re-circulating opposite frequency shifting. The proposed method consists of a microwave sign…
Random distributed-feedback Raman fiber lasers (RRFLs) are promising contenders in the applications of remote sensing, biotechnology, imaging, thanks to the unique properties on low coherence and w…
The concept of multi-homodyne coherent detection is used for stealth and secured optical communications, demonstrating a transmission rate of 20 Gbps under negative (in dB) optical signal-to-noise …
Deep neural networks have enabled major progresses in semantic segmentation. However, even the most advanced neural architectures suffer from important limitations. First, they are vulnerable to ca…
An ultra-wideband orbital-angular-momentum (OAM) mode generator has been proposed and demonstrated both theoretically and experimentally, which is based on a helical long period fiber grating (HLPG…
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…
