Abstract

Currently, there are no cheap and compact sources in the mid-infrared range that can be modulated at high frequencies. While hot membranes are common IR sources, their thermal inertia limit the modulation rates to a few tens of Hertz. Moreover, available thermal sources are unpolarized, isotropic, broadband and have a low efficiency. However, there is no fundamental limit that imposes these properties. It turns out that they can be strongly modified by using appropriate nanostructures. In this presentation, we report the design, fabrication and characterization of infrared incandescent sources, modulated faster than 10 MHz with a controlled spectrum and polarization.
