Building an end user focused THz based ultra high bandwidth wireless access network: The TERAPOD approach
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

THz Electronics for Data Centre Wireless Links - the TERAPOD Project
This paper presents an overview of the terahertz (THz) resonant tunneling diode (RTD) technology that will be used as one of the approaches towards wireless data centres as envisioned on the eU H2020 TERAPOD project. We show an example 480 gm Ć 680 gm THz source chip at 300 GHz employing a 4 gm Ć 4 gm RTD device with 0.15 mW output power. We also show a basic laboratory wireless setup with this device in which up to 2.5 Gbps (limited by equipment) was demonstrated
Design of 2D TeraHertz band-gap photonic waveguides using an accelerated integral equation technique
This paper describes the application of the buffered block forward backward (BBFB) method to the problem of modeling 2D terahertz (THz) photonic band gap waveguides at the frequency of 3 THz. The method of moments (MoM) is applied to the integral equation (IE) formulation in order to obtain the linear system that is solved using the BBFB technique. The waveguide dimensions are obtained using the gap map technique

Gallium arsenide whispering gallery mode resonators for terahertz photonics
As the field of terahertz (THz) photonics advances, we present a monolithic
gallium arsenide (GaAs) disk-shaped whispering gallery mode resonator that has
potential as a component in THz nonlinear optics. GaAs is a material with
significant optical nonlinearity which can be enhanced when the crystal is
shaped into a microdisk resonator. A 4-mm-disk-resonator was fabricated using
single-point diamond turning and was characterised to obtain a quality (Q)
factor of 2.2k at ~150 GHz and 1.4k at ~300 GHz. We also demonstrated the
blue-shifting of up to ~0.3 GHz of the THz modes using a block of metal. This
post-fabrication degree of freedom could be useful for phase-matching
requirements for nonlinear optical processes, such as detection based on
optical up-conversion of THz radiation. Such a compact, tunable and efficient
device could be integrated into nonlinear photonic platforms for THz
generation, manipulation and detection.Comment: 8 pages, 5 figure
