Conceived over 30 years ago, photoconductive (PC) emitters have proved essential in the
development and spread of terahertz technology. Since then, not only have they been used …

We present an optoelectronic mixer for the terahertz (THz) frequency-domain based on an
iron-doped InGaAs layer integrated in a plasmonic microcavity. We show that this structure …

This chapter focuses on the generation of continuous waves in the Terahertz (THz)
frequency range by using the optical heterodyne, also called photomixing of two slightly …

We proposed and investigated a novel terahertz free-electron laser, which is based on two
gratings driven by two electron-beams. Two gratings are symmetrically arranged to form an …

A modified Smith-Purcell free-electron-laser based on two tandem cylindrical-gratings is
proposed. The preset grating with larger size, operating in the slow-wave condition, is to …

Summary This chapter emphasizes Terahertz (THz) metrology–one of the most problematic
and daunting topics in the THz field, especially the measurement of THz power. Through …

This paper reviews promising materials for compact sources and detectors for terahertz
pulses via 1.55 μm photoconductive switches. We begin with a brief description of …

Investigations were made for optimizing ZnTe as a THz detector at 1560-nm probe beam
wavelength, and was compared with its performance at 780 nm. High-sensitive THz …

We report the generation mechanism associated with nano-grating electrode photomixers
fabricated on Fe-doped InGaAsP substrates. Two different emitter designs incorporating …

We present continuous-wave terahertz (cw THz) detectors employing iron doped InGaAs as
photoconductive material. The iron doped photoconductor shows improved properties …
