• Gallium Arsenide‐Based Active Antennas for Optical

     · Although gallium arsenide (GaAs) is one of the most commonly used semiconductor substrate materials its intrinsic bandgap of 1.42 eV hinders the use of GaAs photodetectors for optical communication. In this study hot-electron-based GaAs active antenna devices are demonstrated displaying photoresponses well below the bandgap at the

  • Bespoke gallium arsenide optical components FLIR Forward

     · Like other semiconducting materials gallium arsenide has an optical bandgap though unlike germanium and silicon it has a direct bandgap with its intrinsic edge at 0.87µm. Transmitting at around 40 between 2-15µm with a low absorbance a broadband antireflective (BBAR) coating can be applied to increase its spectral performance.

  • Optical Absorption of Gallium Arsenide between 0.6 and

    The optical absorption coefficient of high-resistivity gallium arsenide has been measured over the range of photon energy 0.6 to 2.75 eV at temperatures from 10 to 294ifmmode circelsetextdegreefi K. The main absorption edge shows a sharp peak due to the formation of excitons. The energy gap and exciton binding energy are deduced from the shape of the absorption curve above the edge.
