Abstract

The invention discloses a GaAs-based visual terahertz detection display chip, which relates to the technical field of terahertz wave. The display chip comprises a GaAs Schottky detector diode, a DC detection control output circuit and a GaAs-based LED, wherein an output end of the GaAs Schottky detector diode is connected with an input end of the DC detection control output circuit; The output endof the DC detection control output circuit is connected with the input end of the GaAs-based LED, the GaAs-based LED is used for lighting according to the current output by the GaAs Schottky detection diode, and the intensity of the terahertz signal is judged by observing the intensity of the GaAs-based LED light emission. The output end of the DC detection control output circuit is connected with the input end of the GaAs-based LED. The chip can realize terahertz detection and display, can realize homogeneous integration, high integration level, simple process, small size of a single chip, and can realize array.

Description

technical field [0001] The invention relates to the technical field of terahertz waves, in particular to a GaAs-based visual terahertz detection and display chip. Background technique [0002] Terahertz (THz) waves refer to electromagnetic waves with a frequency in the range of 0.3THz-3THz. The generalized terahertz wave frequency refers to 100GHz to 10THz, where 1THz=1000GHz. THz waves occupy a very special position in the electromagnetic spectrum, and THz technology is recognized as a very important cross-frontier field by the international scientific and technological community. [0003] Since the terahertz frequency band is in a section of electromagnetic frequency between microwave and infrared optics, in the infrared light frequency band, especially the near-infrared optical frequency band, since both terahertz and infrared are outside the range of human perception, the human eye cannot judge terahertz It is a very direct means of visual inspection to determine whethe...
