“…Due to their superior speed performance, DBQW RTDs can be also used to realise high-sensitivity THz detectors [81] [82], and can operate both as standard direct [119], as well as coherent [143], detectors according to the specific bias point [144], as illustrated in Fig. 15.…”

“…In this case, the RTD is biased within its NDR region and the circuit acts as a local oscillator (LO) [160]. If the incoming carrier frequency f c is close enough to the LO one, injection locking [161] takes place and the two signals synchronise [162], performing coherent homodyne detection [143]. At the same time, the incoming signal is demodulated through the non-linear mixing properties of the NDR region [163], where the RTD acts as a self-oscillating mixer [145].…”

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.

“…In the region (Ⅰ), where the outside of the self-oscillation region and the NDC region is far away, only envelope detection using the nonlinearity of the RTD occurs. The second is coherent detection, which operates by applying a bias voltage in the self-oscillation region (region(Ⅱ)) [28] [29]. Homodyne detection is performed by combining the injection-locking phenomenon and selfoscillating mixing operation.…”

In modern optical communications, pulse amplitude modulation 4 (PAM4) is employed to achieve higher data rates than that achieved by conventional non-return-to-zero format. Meanwhile, there is an increasing interest to convert wired connections to wireless in data centers using high-speed millimeter-wave and terahertz (THz) links. Here, we introduced the PAM4 modulation for THz wireless communications using a resonant tunneling diode (RTD) receiver. Compared with a Schottky-barrier diode receiver, the RTD receiver has higher sensitivity, and a stronger nonlinearity at low input power when it is operated with an amplified detection scheme. We achieved 24-Gbaud (48-Gbit/s) transmission in the 300-GHz band with a quasi-real-time digital signal processing (DSP), which is the fastest PAM4 wireless communication without an offline DSP to the best of our knowledge.

“…Compared to other electronic device technologies that may be used in the 0.1 -1 THz band such as transistors, Gunn diodes, etc., the RTD exhibits the largest bandwidth (for a given device size), requires simple circuitry, is compact, and consumes low power [7]. Recently, high performance RTD based THz short range multigigabit wireless links [8]- [10] and imaging applications have been demonstrated [11]. Thus, the accurate modelling of RTDs to support reliable THz circuit design is of paramount importance.…”

This paper presents a novel, on-wafer de-embedding technique for the accurate small-signal equivalent circuit modelling of resonant tunneling diodes (RTDs). The approach is applicable to stabilised RTDs, and so enables the modelling of the negative differential resistance (NDR) region of the device's current-voltage (I-V) characteristics. Further, a novel quasianalytical procedure to determine all the equivalent circuit elements from the de-embedded S-parameter data is developed. Extraction results for a 10 x 10 µm 2 stabilised, low-current density RTD at different bias points show excellent fits between modelled and measured S-parameters up to 110 GHz.Index Terms-Bias oscillations, experimental modelling, parameter extraction, Resonant tunneling diode (RTD), smallsignal equivalent circuit. Lisbon. His current research interests include applications of resonant tunneling diodes and resonant tunneling diode based optoelectronic devices, and neural-inspired photonic circuits.
