An Analog Signal Processing EIC-PIC Solution for Coherent Data Center Interconnects

no code implementations18 Feb 2022 Shivangi Chugh, Rakesh Ashok, Punit Jain, Sana Naaz, Aboobackkar Sidhique, Shalabh Gupta

In this brief, for the first time, we present integration of a silicon photonic integrated coherent receiver (ICR) module with a CPR module, as a part of a complete coherent receiver solution.

An Endless Optical Phase Delay for Phase Synchronization in High-Capacity DCIs

no code implementations17 Jun 2021 Rakesh Ashok, Sana Naaz, Shalabh Gupta

In this work, we propose and demonstrate a module to linearly add an arbitrary amount of continuous (reset-free) phase delay to an optical signal.

MRRT: Multiple Rapidly-Exploring Random Trees for Fast Online Replanning in Dynamic Environments

no code implementations22 Apr 2021 Zongyuan Shen, James P. Wilson, Ryan Harvey, Shalabh Gupta

Specifically, the edge pruning procedure checks the collision status through the tree and only removes the invalid edges while maintaining the tree structure of already-explored regions.
