Reconfigurable and nonvolatile graphene photodetector integrated onto photonic crystal waveguide

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

A reconfigurable and nonvolatile graphene photodetector integrated graphene and ferroelectric layer onto the air-slotted photonic crystal (PC) waveguide was fabricated and characterized. The device demonstrated nonvolatile positive and negative photocurrents in reconfigurable graphene p-i-n and n-i-p homojunction configurations under telecommunication band laser illumination. This design concept can extend to other two-dimensional semiconductors, offering potential for on-chip optoelectronic synapses, in-memory sensing, computing, and neuromorphic applications.
