Patent number: 9810578Abstract: A radiation detection technique employs field enhancing structures and electroluminescent materials to converts incident Terahertz (THz) radiation into visible light and/or infrared light. In this technique, the field-enhancing structures, such as split ring resonators or micro-slits, enhances the electric field of incoming THz light within a local area, where the electroluminescent material is applied. The enhanced electric field then induces the electroluminescent material to emit visible and/or infrared light via electroluminescent process. A detector such as avalanche photodiode can detect and measure the emitted light. This technique allows cost-effective detection of THz radiation at room temperatures.Type: GrantFiled: March 4, 2016Date of Patent: November 7, 2017Assignee: Massachusetts Institute of TechnologyInventors: Brandt Christopher Pein, Harold Young Hwang, Wendi Chang, Keith A.
