2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/108330We have developed a detector of coherent terahertz (THz) radiation that can recover the full polarisation state of a THz transient. The device is three-contact photoconductive receiver, which is capable of recording two time-varying electric field components of a THz pulse simultaneously. Our receiver was fabricated on Fe+ implanted InP and showed a cross-polarised extinction ratio greater than 100:1. The detector will be useful for spectroscopy of birefringent and optically active materials.2 pages, 3 figures, conference abstractOther Condensed Mattertext
