An On-Chip Continuous Wave Terahertz Spectrometer
James Seddon, Chris Graham, Marie Georgiades +2
Continuous Wave (CW) Terahertz spectroscopy enabled by photomixing is a promising high precision spectroscopic tool for the examination of a wide variety of samples including biolo…
High performance waveguide uni-travelling carrier photodiode grown by solid source molecular beam epitaxy
Xiaoli Lin, Michele Natrella, James Seddon +6
The first waveguide coupled phosphide-based UTC photodiodes grown by Solid Source Molecular Beam Epitaxy (SSMBE) are reported in this paper. Metal Organic Vapour Phase Epitaxy (MOV…
Optical communications-based platform uses Uni-Travelling-Carrier Photodiode for ultra-high resolution software-defined THz spectroscopy and reveals LiYF4:Ho intrinsic spectral line shape
Rodolfo I. Hermans, Haymen Shams, James P. Seddon +2
High resolution (900 Hz full-width at half maximum) frequency domain spectroscopy near 0.2Terahertz is achieved using an exact frequency spacing comb-source in the optical communic…
Pilot-tone assisted 16-QAM photonic wireless bridge operating at 250 GHz
Luis Gonzalez-Guerrero, Haymen Shams, Irshaad Fatadin +5
A photonic wireless bridge operating at a carrier frequency of 250 GHz is proposed and demonstrated. To mitigate the phase noise of the free-running lasers present in such a link,…
Monolithic quantum-dot distributed feedback laser array on silicon
Yi Wang, Siming Chen, Ying Yu +12
Electrically-pumped lasers directly grown on silicon are key devices interfacing silicon microelectronics and photonics. We report here, for the first time, an electrically-pumped,…
