Uni-Travelling Carrier photodetectors as THz detectors and emitters

摘要

The THz part of the spectrum (0.1 to 10 THz) has been gathering increasing interest over the past 10 years as it could enable interesting new applications. Key to its exploitation has been the development of photonic based sources and detectors. However there is a lack of room temperature operating devices for both sources and detectors. We propose the use of uni-travelling carrier photodetectors (UTC-PDs) as both source and detectors for the range up to 2 THz.
