Optical interconnects are increasingly important for our communication and data center systems, and are forecasted to be an essential component of future computers. In order to meet these future demands, optical interconnects must be improved to consume less power than they do today. To do this, both more effcient transmitters and more sensitive receivers must be developed. This work addresses the latter, focusing on device level improvements to tightly couple a low capacitance photodiode with the first...

In the past couple of decades we have seen remarkable advances in the integration of biological systems with artificial ones. Our knowledge of both of these worlds has grown exponentially, and in particular our knowledge of the human body. In recent years we have been able to understand and treat diseases we never thought we would, and we have even been able to interface with the body to restore lost functions. Direct interaction with the human brain to read and write information to it has been achieved thanks to the...

An offset, gap-closing capacitive MEMS strain sensor for detecting strain of steel has been designed, fabricated, and tested both in isolation and bonded to steel. This extensometer approach benefits from low sensitivity to thermal noise typical of capacitive sensors. The design utilizes an offset parallel-plate array design so that we can achieve differential sensing in a single device lay...
