Lithium tantalate photonic integrated circuits for volume manufacturing

Tobias Kippenberg, Mikhail Churaev, Xinru Ji, Zihan Li, Alisa Davydova, Junyin Zhang, Yang Chen, Xi Wang, Kai Huang, Chen Yang

Electro-optical photonic integrated circuits (PICs) based on lithium niobate (LiNbO3) have demonstrated the vast capabilities of materials with a high Pockels coefficient1,2. They enable linear and high-speed modulators operating at complementary metal–oxi ...

Control Interface for Hands-free Navigation of Standing Mobility Vehicles based on Upper-Body Natural Movements

Diego Felipe Paez Granados, Chen Yang

In this paper, we propose and evaluate a novel human-machine interface (HMI) for controlling a standing mobility vehicle or person carrier robot, aiming for a hands-free control through upper-body natural postures derived from gaze tracking while walking. ...

Digitally controlled analog proportional-integral-derivative (PID) controller for high-speed scanning probe microscopy

Georg Fantner, Maja Dukic Pjanic, Nahid Hosseini, Adrian Pascal Nievergelt, Santiago Harald Andany, Chen Yang

Nearly all scanning probe microscopes (SPMs) contain a feedback controller, which is used to move the scanner in the direction of the z-axis in order to maintain a constant setpoint based on the tip-sample interaction. The most frequently used feedback con ...

Probing the Morphology and Evolving Dynamics of 3D Printed Nanostructures Using High-Speed Atomic Force Microscopy

Georg Fantner, Maja Dukic Pjanic, Chen Yang, Jie Zhao

Focused electron beam induced deposition (FEBID) has been demonstrated as a promising solution for synthesizing truly three-dimensional (3D) nanostructures. However, the lack of morphological feedback during growth complicates further development toward hi ...

Design of a high-bandwidth tripod scanner for high speed atomic force microscopy

Georg Fantner, Chen Yang, Nahid Hosseini, Maja Dukic Pjanic, Jie Zhao

Tip-scanning high-speed atomic force microscopes (HS-AFMs) have several advantages over their sample-scanning counterparts. Firstly, they can be used on samples of almost arbitrary size since the high imaging bandwidth of the system is immune to the added ...
