Seebeck nanoantennas for the detection and characterization of infrared radiation Briones, Edgar Cuadrado, Alexander Briones, Joel Díaz de León, Ramón Martínez Antón, Juan Carlos McMurtry, Stefan Hehn, Michel Montaigne, François Alda Serrano, Javier González, Francisco Javier Arrays of metallic thermocouples in the shape of spiral nanoantennas are proposed as infrared detectors, which use the thermoelectric properties of the metallic interfaces to generate electrical DC signals. The responsivity of these types of antennas is evaluated from both theoretical and numerical perspectives pointing out its potential as infrared sensors. Moreover, the same structures can be used to characterize the state of polarization of the optical near fields with a spatial resolution comparable to the wavelength. 2023-06-19T13:32:56Z 2023-06-19T13:32:56Z 2023-06-19T13:32:56Z 2014-09-17 journal article https://hdl.handle.net/20.500.14352/33991 1094-4087 10.1364/OE.22.0A1538 eng project “Centro Mexicano de Innovación en Energía Solar” grant CV-45809 project 3120059 Project ENE2009-013430 restricted access Optical Society of America (OSA)
