“…Figure 9 (a) shows the band diagram of the photodiode optimized for the operation at 300-400 GHz, which is a modification of the UTC-PD. The photodiode chip was packaged into the module with a rectangular waveguide (WR-3) output port [19]. Figure 9 (b) shows the frequency dependence of the output power generated from the module.…”

The increasing demand of unoccupied and unregulated bandwidth for wireless communication systems will inevitably lead to the extension of operation frequencies toward the lower THz frequency range. Higher carrier frequencies will allow for fast transmission of huge amounts of data as needed for new emerging applications. Despite the tremendous hurdles that have to be overcome with regard to sources and detectors, circuit and antenna technology and system architecture to realize ultrafast data transmission in a scenario with extensive transmission loss, a new area of research is beginning to form. In this article we give an overview of emerging technologies and system research that might lead to ubiquitous THz communication systems in the future.

“…So far, the best output power achieved is around 1 mW at 300 GHz for both UTC-PDs [18] and RTDs [14]. To further increase the output power, two or more devices could be combined and this has been done with two UTC-PDs providing more than 1 mW at 300 GHz [19], but quite close to device destruction.…”

Abstract-The TERAPOD project aims to investigate and demonstrate the feasibility of ultra high bandwidth wireless access networks operating in the Terahertz (THz) band. The proposed TERAPOD THz communication system will be developed, driven by end user usage scenario requirements and will be demonstrated within a first adopter operational setting of a Data Centre. In this article, we define the full communications stack approach that will be taken in TERAPOD, highlighting the specific challenges and aimed innovations that are targeted.

“…As for O/E converters, we use a uni-traveling-carrierphotodiode (UTC-PD), which satisfies both wide bandwidth and high output power [10]. The J-band UTC-PD module has a 3-dB bandwidth of over 100 GHz, and a typical output power of over 100 μW at 300 GHz for a photocurrent of 10 mA [11]. A photoconductive antenna is another wellknown O-E converter, which can operate at THz frequencies, but is more suitable for the pulse generation with high peak current [12].…”

SUMMARYThis paper describes recent progress of photonicallyenabled systems for millimeter-wave and terahertz measurement applications. After briefly explaining signal generation schemes as a foundation of photonics-based approach, system configurations for specific applications are discussed. Then, practical demonstrations are presented, which include frequency-domain spectroscopy, phase-sensitive measurement, electric-field measurement, and 2D/3D imaging.
