“…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].…”

“…The main limitation of RTD oscillators has been their low output power (in the tens of microwatts range), but relatively high output power for some of these oscillators is now being reported, e.g. 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].…”

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.

“…An RTD with a light absorption layer, the RTD photo-detector (RTD-PD), shows great potential applications for opticalelectrical modulation and photo-detection [3]. This device can benefit from the RTDs capability of high frequency operation, and so millimeter-wave (mm-wave) RTD-PD oscillators have been realised and are also reported here.…”

“…The resonant tunneling diode (RTD) has received considerable attention recently for realizing THz sources [2,3]. Of all present solid-state sources, it has the highest demonstrated oscillation frequency of 1.92 THz [3]. Other advantages of the RTD include room temperature operation, compact size, and potential for optical control, among others.…”

“…Due to the lack of compact and high power THz sources operating at room temperature, the THz frequency is the less developed spectrum, especially in the 0.1 -3 THz range.

Of all present solid-state sources, it has the highest demonstrated oscillation frequency of 1.92 THz [3].…”

Upcoming THz applications require compact, robust, and efficient sources with high output‐power. Among electronic devices, resonant tunneling diodes (RTDs) have been shown to be a promising candidate for THz operation. Triple barrier resonant tunneling diodes provide a high degree of design and operation freedom. Zero‐bias detection and THz emission is possible with the same device due to the asymmetric structure and IV curve. However, more investigations in the layer stack design are required. We present an investigation into the effect of collector spacer thickness and doping profile in the subcollector contact region. The aim is to simultaneously optimize the RF output‐power and cut‐off frequency in triple barrier structures. A series of devices with different collector spacers and two distinct doping profiles are fabricated. We observe a trade‐off between collector spacer thickness and doping profile for either higher output‐power or cut‐off frequency. In addition, we present simulation results from a Non‐Equilibrium Green’s Function solver implemented in Python. Here, we observe a need for accurate determination of the extent of the non‐equilibrium region to achieve simulation results matching the IV measurements.This article is protected by copyright.
