Large-Scale Crosstalk-Corrected Thermo-Optic Phase Shifter Arrays in Silicon Photonics

Posted by klaurent Caltech

Kavli Affiliate: Ali Hajimiri | Summary:We introduce a thermo-optic phase shifter (TOPS) array architecture with independent phase control of each phase shifter for large-scale and high-density photonic integrated circuits with two different control schemes: pulse amplitude modulation (PAM) and pulse width modulation (PWM). We realize a compact spiral TOPS and a 288-element high-density row-column TOPS […]

NeMF: Neural Motion Fields for Kinematic Animation

Posted by klaurent UCAS

Kavli Affiliate: Yi Zhou | First 5 Authors: Chengan He, Jun Saito, James Zachary, Holly Rushmeier, Yi Zhou | Summary: We present an implicit neural representation to learn the spatio-temporal space of kinematic motions. Unlike previous work that represents motion as discrete sequential samples, we propose to express the vast motion space as a continuous […]

Leveraging place field repetition to understand positional versus nonpositional inputs to hippocampal field CA1

Posted by klaurent Hopkins

Kavli Affiliate: James Knierim | Authors: William Hockeimer, Ruo-Yah Lai, Maanasa Natrajan, William Snider and James J. Knierim | Summary: The hippocampus is believed to encode episodic memory by binding information about the content of experience within a spatial framework encoding the location of that experience. Previous work implies a distinction between positional inputs to […]
