With the optimized MUTC-PD design, the collapse of the electric field will be greatly suppressed, and the electrons in its collection layer will gradually reach their peak velocity with the growing incident light power. Moreover, as the incident light intensity increases, the differential capacitance also declines, thus the total bandwidth grows. It will make the MUTC-PD achieve high-speed and high-power response performance simultaneously. Based on simulation, for 16\u03bcm MUTC-PD with a 70 nm cliff layer, the maximum 3 dB bandwidth at \u22125 V is 137 GHz, compared with 64 GHz for the MUTC-PD with a 30 nm cliff layer. The saturation RF output power is 27.4 dBm at 60 GHz.<\/jats:p>","DOI":"10.3390\/s24072020","type":"journal-article","created":{"date-parts":[[2024,3,22]],"date-time":"2024-03-22T05:10:53Z","timestamp":1711084253000},"page":"2020","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Modified Uni-Traveling-Carrier Photodetector with Its Optimized Cliff Layer"],"prefix":"10.3390","volume":"24","author":[{"given":"Xiaowen","family":"Dong","sequence":"first","affiliation":[{"name":"State Key Laboratory of Information Photonics and Optical Communications, School of Electrical and Electronic Engineering, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kai","family":"Liu","sequence":"additional","affiliation":[{"name":"State Key Laboratory of Information Photonics and Optical Communications, School of Electrical and Electronic Engineering, Beijing University of Posts and Telecommunications, Beijing 100876, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2024,3,22]]},"reference":[{"key":"ref_1","first-page":"66","article-title":"Terahertz wireless communications for 2030 and beyond: A cutting-edge frontier","volume":"59","author":"Chen","year":"2021","journal-title":"IEEE Commun.
