Polarisation-sensitive terahertz detection by multicontact photoconductive receivers

Castro-Camus, E.; Lloyd-Hughes, J.; Johnston, M. B.; Fraser, M. D.; Jagadish, C.; Tan, Hark Hoe


We have developed a terahertz radiation detector that measures both the amplitude and polarization of the electric field as a function of time. The device is a three-contact photoconductive receiver designed so that two orthogonal electric-field components of an arbitrary polarized electromagnetic wave may be detected simultaneously. The detector was fabricated on Fe+ ion-implanted InP. Polarization-sensitive detection is demonstrated with an extinction ratio better than 100:1. This type...[Show more]
