High-power RF photodiodes and their applications

چکیده
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 the bandwidth and output power of photodiodes are discussed, and promising applications to broadband wireless communications and spectroscopic sensing are described. Photodiode chip is bonded to the substrate with the antenna. This is a symbolic figure of RF photonics in this article. Antenna Photodiode Light

Improved RF Power Extraction from 1.55�m Ge/Si n-i-p Photodiodes with Load Impedance Optimization
High power photodiodes (PDs) improve signal fidelity in high-speed optoelectronic communications links by eliminating a post amplifier stage, which reduces noise figure, decreases RF insertion loss, and increases spur-free dynamic range [1][2]. Recent efforts have focused on developing photodiodes with high power handling capabilities, and a photodiode with a compression current of 199 mA has b...

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...

We report on the first demonstration of velocity-matched distributed photodetectors and balanced photodetectors with p-i-n photodetectors. Record-high linear dc photocurrent of 45 mA has been achieved without suffering from thermal damage, thanks to the superior power handling capability of p-i-n photodiodes. A novel fiber alignment technique has been developed to achieve high linear photocurre...
