“…Note that R st establishes the maximum device size A max = 2∆V /3∆JR st which can be used to realise an oscillator [117]. The resonating inductance L is usually realised from a short section of a transmission line, such as a coplanar waveguide (CPW) [118], a coplanar stripline (CPS) [119], or a microstrip line [120], where 2πf osc L = Z 0 tan(βl), being β the phase constant, l the length of the stub, and Z 0 its characteristic impedance, while the resonating capacitance is provided by the intrinsic self-capacitance of the diode. This is often the case for RTD oscillators operating below ∼ 300 GHz, where an external load is employed [83].…”

Resonant tunnelling diode (RTD) technology is emerging as one of the promising semiconductor-based solidstate technologies for terahertz (THz) wireless communications. This paper provides a review of the state-of-the-art, with a focus on the THz RTD oscillator, which is the key component of RTDbased THz transmitters and coherent receivers. A brief summary on the device principle of operation, technology, modelling, as well as an overview of oscillator design and implementation approaches for THz emitters, is provided. A new insight to device evaluation and to the reported oscillator performance levels is also given, together with brief remarks on RTD-based THz detectors. Thereafter, an overview of the reported wireless links which utilise an RTD in either transmission or reception, or in both roles, is given. Highlight results include the record single-channel wireless data rate of 56 Gb/s employing an all RTD-based transceiver, which demonstrates the potential of the technology for future short-range communications. The paper concludes with a discussion of the current technical challenges and possible strategies for future progress.

“…up to 1mW at 300 GHz with large micron-sized devices (by members of the present consortium) [12] and 0.6 mW at 620 GHz with a two-element array by a Japanese group [13]. RTDs with 1mW at 300 GHz were developed on the H2020 iBROW project including oscillators with record output powers in the 0.5-1mW range at 300 GHz [12], [14], [15]. Suitable antennas for integration with these oscillators have also been developed [16].…”

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.
