Abstract

A micro-nanofiber structure based wide-spectrum graphene photoconductive detector in the technical field of optical fiber communication is disclosed. The wide-spectrum graphene photoconductive detector comprises a substrate, micro-nanofiber, a graphene thin film, a metal electrode and bias voltage, wherein the metal electrode is manufactured on the substrate; the graphene thin film is manufactured on the metal electrode and divides the metal electrode into a first electrode and a second electrode; the micro-nanofiber and the graphene thin film are in contact; and the bias voltage is connected with the first electrode and the second electrode. The micro-nanofiber structure based wide-spectrum graphene photoconductive detector has the advantages of wide-spectrum detection, high detection efficiency, low insertion loss and simple structure.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to a wide-spectrum graphene photoconductive detector based on a micro-nano optical fiber structure. Background technique [0002] With the maturity of photodetection technology and the gradual expansion of application scope, the requirements for detection rate, effective wavelength and sensitivity of detectors are getting higher and higher, and the rapid development of CMOS technology also requires the gradual development of photodetectors towards integration. Graphene can absorb energy in a broad spectrum range to generate electron-hole pairs, making broadband photodetection possible from infrared to visible to ultraviolet and megahertz bands; and graphene can be perfectly integrated with highly integrated silicon-based devices. It has great advantages in low power consumption and large-scale integration. [0003] After searching the existing technologies, it w...
