Using photonic crystals to enhance the efficiency of optical devices has been a widely discussed concept since its advent in the early 90s. The focus of this study is on detector enhancement using resonant cavity structures. Cavity resonators confine light such that it allows recycling of unabsorbed photons; this simple mechanism enhances the detector’ s efficiency without directly changing the device’ s parameters. In this work, we will assess the enhancement factor of 1088 different structures. In addition, we will build a model in a semiconductor device simulation software that will highlight the structural effects on absorption. With a focus on the near infrared band, the implementation of photonic structures in Silicon will allow for low-cost infrared sensors and LIDAR technologies.

“For the past two years, I have been gradually becoming more exposed to research in optics. After working for more than four semesters, I feel ready to take that experience to a more challenging setting. Also, the idea of applying the knowledge I’ ve gathered so far into one cohesive work is something I hope to gain from this SuperUROP.”
