Graphene-incorporated plasmo-thermomechanical infrared radiation detection

Plasmo-thermomechanical suspended nanowire array detectors for mid-infrared spectrum

We propose a plasmo-thermomechanical mid-infrared detector operating at 4.3 μm wavelength. The design utilizes an array of the bimetallic fishbone nanowires that are suspended 50 nm above a 1.5 μm × 0.3 μm silicon nitride waveguide to create a leaky wave radiation. Moreover, the thermo-mechanically actuated nanowire will induce evanescent wave modulation that can be detected by the leaky wave o...

Plasmonically enhanced thermomechanical detection of infrared radiation.

Nanoplasmonics has been an attractive area of research due to its ability to localize and manipulate freely propagating radiation on the nanometer scale for strong light-matter interactions. Meanwhile, nanomechanics has set records in the sensing of mass, force, and displacement. In this work, we report efficient coupling between infrared radiation and nanomechanical resonators through nanoante...

Electronic modulation of infrared radiation in graphene plasmonic resonators.

All matter at finite temperatures emits electromagnetic radiation due to the thermally induced motion of particles and quasiparticles. Dynamic control of this radiation could enable the design of novel infrared sources; however, the spectral characteristics of the radiated power are dictated by the electromagnetic energy density and emissivity, which are ordinarily fixed properties of the mater...

Remote Detection of Cat by Infrared Radiation

Several years ago, it was established by the work of P. W. Kadlec of Eastern Airlines (Project TRAPCAT, Ref. 1), that clear air turbulence was frequently associated with temperature gradients or discontinuities in the atmosphere. Barnes Engineering Company had just completed the development of the Satellite Infrared Spectrometer (SIRS) for the Weather Bureau for remote atmospheric temperature p...
