E&P Research Overview

Electronics & Photonics research at UC Santa Barbara spans a wide spectrum of topics: material growth, compound semiconductors, high performance transistors, quantum devices, photonics, integrated circuits, low power design, optics, and systems/devices.

We design and build new semiconductors, transistors that are faster, communication channels with higher bandwidths, devices with lower power requirements, metamaterials with new capabilities, integrated photonics devices with unprecedented performance, and more. The results of our research form the building blocks for new systems and devices for sensing, communication, and computing.

Faculty in Electronics & Photonics are multidisciplinary and enthusiastically collaborative. There is a risk-tolerant spirit of bold exploration to cooperatively push the frontiers. This culture, combined with unique state-of-the-art facilities for characterization, growth, and micro fabrication, allows students and researchers to engage in cutting edge research activities. There is also an intense focus on transferring today's research activities into commercial enterprises, as evidenced by the rich portfolio of start-up activities and industry partnerships from this group.
