Editor's Choice: Metamaterial Engineering for Superior HgTe cQD Photodetector Performance
Highly responsive, low noise, and inexpensive photodetectors that operate in the mid-infrared (MIR) wavelength regime are in high demand forapplications ranging from fundamental science to large scale industries. In this work, mercury telluride (HgTe) colloidal quantum dot (cQD) based photodetectors are systematically improved by the introduction of new metamaterial designs.
Editor's Pick: Measuring dielectric and electro-optic responses of thin films using plasmonic devices
This paper introduces a simple method for the measurement of the relative permittivity and the Pockels coefficient of electro-optic (EO) materials in a waveguide up to sub-THz frequencies. By miniaturizing the device and making use of plasmonics, the complexities of traditional methods are mitigated. This work elaborates the fabrication tolerance and simplicity of the method, and highlights its applicability to various materials, substrates and configurations.
Science Publication: Graphene photodetector shows unprecedented speed
Optical data communication requires an ever-growing need for faster devices. Scientists of the Institute of Electromagnetic Fields (IEF) have developed the world’s fastest photodetector up to this point. The combination of metamaterials and graphene has led to the record breaking >500 GHz bandwidth. These devices could pave the way for the next generation highest speed photodetectors.
