Ultra-Fast Photodiodes for Terahertz Generation
نویسندگان
چکیده
Recent progress in the development of Continuous Wave Terahertz sources based on Ultra-Fast Photodetectors operating at 1.55 μm is reported. The Uni-Travelling Carrier Photodiode is realised as a broadband and high-efficiency photomixer while the frequency response advantage of employing a travelling wave design is demonstrated. State-of-the-art bandwidth-efficiency product from Coplanar Waveguide integrated devices was measured. Antenna-integrated devices achieved record levels of Continuous Wave generated power together with record Terahertz figure of merit (PTHz/Popt 2 in W -1 ).

High-power RF photodiodes and their applications
There has been an increasing interest in photonic generation of RF signals in the millimeter-wave (30GHz ∼ 300GHz) and/or terahertz-wave (0.1 THz ∼ 10THz) regions, and photodiodes play a key role in it. This paper reviews recent progress in the high-power RF photodiodes such as UniTraveling-Carrier-Photodiodes (UTC-PDs), which operate at these frequencies. Several approaches to increasing both ...

Inherit advantage of back-illumination in our devices offers an easier integration and layout packaging via flip-chip hybridizati...
متن کاملHigh-Power RF Uni-Traveling-Carrier Photodiodes (UTC-PDs) and Their Applications
Research on exploring millimeter waves and/or terahertz (THz) waves, which cover the frequency range from 30 GHz to 10 THz, has lately increased since the nature of these electromagnetic waves is suited to spectroscopic sensing as well as to ultra-broadband wireless communications. One of the obstacles to developing applications of millimeter waves and terahertz waves is a lack of solid-state s...
متن کاملPharmaceutical Analysis using Terahertz Spectroscopy
TERAHERTZ LIGHT Terahertz (THz=10Hz) radiation represents the last unexplored frontier of the radio wave and light spectrum. The so-called ‘Terahertz Gap’ encompasses frequencies invisible to the naked eye in the range from 100GHz (10Hz) up to roughly 30THz (3x10Hz). The former limit lies just above the microwave region, whereas the latter limit is located adjacent to infrared frequencies; the ...
