Photonic Bayesian Neural Networks: Leveraging Programmable Noise for Robust and Uncertainty‐Aware Computing

open access: yesAdvanced Science, EarlyView.
This work introduces a novel photonic Bayesian neural network architecture that utilizes tunable photonic random number generators to independently control weight distribution parameters, significantly improving robustness, scalability, and accuracy while demonstrating practical applications in multimodal data processing and uncertainty‐aware computing.

Inhomogeneous Gain Saturation in EDF: Experiment and Modeling

open access: yes, 2011
Erbium-Doped Fiber Amplifiers can present holes in spectral gain in Wavelength Division Multiplexing operation. The origin of this inhomogeneous saturation behavior is still a subject of controversy.

Colorectal Cancer Cells–Derived Exosomal PIK3CA Mutation DNA Promotes Tumor Metastasis by Activating Fibroblast and Affecting Tumor Metastatic Microenvironment

open access: yesAdvanced Science, EarlyView.
PIK3CAH1047R DNA in colorectal cancer (CRC) cell‐derived exosomes can be delivered into recipient fibroblasts, where it is transcribed and translated, leading to the activation of fibroblasts into cancer‐associated fibroblasts, which secrete elevated levels of IL6. The simultaneous detection and targeting of PIK3CAH1047R mutation and IL6 may serve as a

Multi‐Wavelength Achromatic 3D Meta‐holography with Zoom Function

open access: yesAdvanced Science, EarlyView.
Due to the wavelength mismatch, chromatic aberrations are inevitable in multi‐wavelength meta‐holography. Moreover, since the meta‐hologram is difficult to be refreshed, zoom meta‐holography has not been reported to date. This study proposes a multi‐wavelength achromatic 3D meta‐holography with a zoom function, breaking through both the chromatic ...

Time and phase alignment of distributed gateways: Theoretical analysis and experimental demonstration

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView., 2023
The performance limitation in multiple‐input multiple‐output (MIMO) feeder links due to time and phase misalignment of the ground stations is investigated. Time and phase distribution over optical fiber is considered as an approach to achieve the synchronization requirements.

Linear and Nonlinear Frequency-Division Multiplexing [PDF]

open access: yesarXiv, 2016
Two signal multiplexing schemes for optical fiber communication are considered: Wavelength-division multiplexing (WDM) and nonlinear frequency-division multiplexing (NFDM), based on the nonlinear Fourier transform (NFT). Achievable information rates (AIRs) of NFDM and WDM are compared in a network scenario with an ideal lossless model of the optical ...
