Monolithically Integrated Terahertz Optoelectronics

We present a Monolithically Integrated Terahertz Optoelectronics platform, which leverages QW structures to integrate all terahertz photonic system components onto a single chip. Utilizing photomixing in QW PIN photodiodes, we demonstrate frequency-tunable terahertz generation and detection with significantly improved power efficiency and sensitivity compared to previous devices.
