Highly Sensitive Dispersion Characterization of mm‐Length Silicon Nitride Waveguides and Their Couplers Around the Zero‐Dispersion Wavelength

open access: yesAdvanced Optical Materials, Volume 13, Issue 5, February 13, 2025.
Quantifying the dispersion of on‐chip photonic components is quintessential but remains challenging, especially if the dispersion is weak. Here, a new dispersion measurement technique based on time‐of‐flight and spatial light modulator technology is presented and applied to silicon nitride waveguides and couplers.

An AI based cross‐language aspect‐level sentiment analysis model using English corpus

open access: yesEngineering Reports, Volume 6, Issue 12, December 2024.
First, a multi‐channel XLNet (Multi‐XLNet) model is used to extract contextual information from the text. Then, in the RCNN module, the contextual features are output by the forward and reverse series GRU (BiGRU) to extract deeper emotional features. Finally, the multi‐head attention mechanism obtains text attention emotion representation.
