UTC Photodiodes on Silicon Nitride Enabling 100 Gbit/s Terahertz Links at 300 GHz

Dennis Maes, Sam Lemey, Gunther Roelkens, Mohammed Zaknoune, Vanessa Avramovic, Etienne Okada, P. Szriftgiser, Emilien Peytavit, Guillaume Ducournau, Bart Kuyken

By means of micro-transfer-printing, we bring high-speed UTC photodiodes to a SiN-platform. These waveguide-coupled photodiodes show a responsivity of 0.3 A/W and a bandwidth of 155 GHz. We further demonstrate that direct photomixing at 300 GHz is possible and enables data rates up to 128 Gbit/s...

High-Bandwidth Photodiodes on Silicon Nitride Supporting Net Bitrates in Excess of 350 Gbit/s

Dennis Maes, Qian Hu, Robert Borkowski, Yannick Lefevre, Gunther Roelkens, Sam Lemey, Emilien Peytavit, Bart Kuyken

Silicon-nitride-based integrated photonic platforms currently lack fast photodiodes, limiting its adoption for high-speed optical transceivers. We show uni-traveling-carrier (UTC) photodiodes heterogeneously integrated by means of micro-transfer-printing and demonstrate their excellent bandwidth...

A Coarse-to-Fine Segmentation Methodology Based on Deep Networks for Automated Analysis of Cryptosporidium Parasite from Fluorescence Microscopic Images

Ziheng Yang, Halim Benhabiles, Feryal Windal, Jérôme Follet, Anne-Charlotte Leniere, Dominique Collard

In this paper, we present a deep learning-based framework for automated analysis and diagnosis of Cryptosporidium parvum from fluorescence microscopic images. First, a coarse segmentation is applied to roughly delimit the contours either of individual parasites or of grouped ones in the form of a...

High‐Performance Semitransparent Organic Solar Cells: From Competing Indexes of Transparency and Efficiency Perspectives

Tao Xu, Yiran Luo, Shiwei Wu, Baozhong Deng, Shi Chen, Yunbo Zhong, Shenghao Wang, Gaëtan Lévêque, Renaud Bachelot, Furong Zhu

Semitransparent organic solar cells (ST-OSCs) offer potentially more opportunities in areas of self-powered greenhouses and building-integrated photovoltaic systems. In this work, the effort to use a combination of solution-processable gold nanobipyramids (AuNBPs)-based hole transporting layer and...
