Description
technical field [0001] The invention relates to the field of signal detection and identification in the photoelectric field, in particular to a broadband terahertz electromagnetic structure for photoelectric detection. Background technique [0002] Photoelectric detection technology is one of the key technologies of modern communication technology. With the rapid increase of communication rate demand, the transmission rate based on copper medium is far from meeting the requirements of current communication technology. High-speed signal transmission technology with optical fiber as the main transmission medium represents With the development direction of future communication technology, the technological trend of "light advances copper and retreats" becomes more and more obvious. The photoelectric detection technology is a key part of optical fiber high-speed signal transmission technology, which plays an important role in optical signal quality detection and device performan...
