infrared millimeter terahertz waves scientific conferences

We present a high-sensitivity and broadband photoconductive terahertz focal-plane array with 63 pixels. We utilize a plasmonic nanoantenna array and an optical diffuser to provide a high spatial overlap between the received terahertz field and the optical pump beam to offer an efficient terahertz detection performance. We experimentally demonstrate more than a 60 dB signal-to-noise ratio and a 2 THz detection bandwidth for all of the pixels of the focal-plane array.
