Journal ArticleDOI
Antenna Integrated THz Uni-Traveling Carrier Photodiodes
TL;DR: This paper develops the key elements to present a simple design tool for the efficient integration of the device with an antenna and presents fabricated device results that show the highest figure of merit to date for photonic THz emitters.
Journal ArticleDOI
Photodiodes for Terahertz Applications
TL;DR: In this article, the authors present a modeling tool for the numerical evaluation of antenna coupled uni-travelling carrier photodiodes and experimental evaluation of the fabricated designs.
Journal ArticleDOI
Efficient compact modelling of UTC-photodiode towards terahertz communication system design
Chhandak Mukherjee,Michele Natrella,James Seddon,Chris Graham,Patrick Mounaix,Cyril C. Renaud,Cristell Maneux +6 more
TL;DR: This multidisciplinary work describes an efficient compact model for Uni-Traveling Carrier photodiodes (UTC PD) which is a key component for OEICs, and marks the first demonstration of a multi-physics, computationally efficient and versatile Compact model for UTC-PDs.
Journal ArticleDOI
Ultra-high-resolution software-defined photonic terahertz spectroscopy
Rodolfo I. Hermans,James Seddon,Haymen Shams,Lalitha Ponnampalam,Alwyn J. Seeds,Gabriel Aeppli +5 more
TL;DR: In this paper, a novel technique for high-resolution 1.5µm photonics-enabled terahertz (THz) spectroscopy using software control of the illumination spectral line shape (SLS) is presented.
Journal ArticleDOI
High performance waveguide uni-travelling carrier photodiode grown by solid source molecular beam epitaxy.
Xiaoli Lin,Michele Natrella,James Seddon,Chris Graham,Cyril C. Renaud,Mingchu Tang,Jiang Wu,Huiyun Liu,Alwyn J. Seeds +8 more
TL;DR: In this article, the first waveguide coupled phosphide-based UTC photodiodes grown by Solid Source Molecular Beam Epitaxy (SSMBE) are reported, which overcomes the major issue associated with the unintentional diffusion of zinc in MOVPE and gives the benefit of the superior control provided by MBE growth techniques without the costs and the risks of handling toxic gases of GSMBE.
