This review is focused on the latest developments in continuous-wave (CW) photomixing for
Terahertz (THz) generation. The first part of the paper explains the limiting factors for …

Device design for unitraveling-carrier photodiodes (UTC-PDs) and their derivative structures
is reconsidered from the point of view of terahertz (THz) applications. A key design …

Terahertz waves, which lie in the frequency range of 0.1-10 THz, have long been
investigated in a few limited fields, such as astronomy, because of a lack of devices for their …

With the mass development of mobile data transfers, wireless communications have recently
entered a new area: the carrier frequency is now entering the THz region. After a brief …

The development of uni-traveling carrier photodiodes over the past 25 years is briefly
reviewed and the key design in their structure are discussed. Monte Carlo simulation run for …

The rapidly increasing demand for higher bandwidth and data rates in wireless
communication systems over the past several decades is well known. Over the last 12 years …

We present a resonant-cavity-enhanced broadband unitraveling carrier photodiode
optimized for terahertz (THz) generation. It uses a novel semitransparent top-contact utilizing …

A frequency doubled erbium doped modelocked fiber frequency comb is used to implement
a THz photomixing synthesizer. The useful THz linewidth is in order of 150 kHz and has …

A wireless transmission system with a remote-supplied hotspot is demonstrated working up
to gigabit data rates. The emission uses a 200 GHz carrier frequency, generated using an …
