This work reviews the design and applicability of beam-forming networks based on Coherently Radiating Periodic Structures (CORPS-BFN) at Terahertz (THz) frequency bands. These versatile networks offer two operation modes: ... -
High saturation photocurrent THz waveguide-type MUTC-photodiodes reaching mW output power within the WR3.4 band
Grzeslo, Marcel; Dülme, Sebastián; Clochiatti, Simone; Neerfeld, Tom; Haddad, Thomas; Lu, Peng; Tebart, Jonas; Makhlouf, Sumer; Biurrun Quel, Carlos ; Fernández Estévez, José Luis; Lackmann, Jörg; Weimann, Nils; Stöhr, Andreas (Optica, 2023)
Artículo / Artikulua
In this paper, we report on waveguide-type modified uni-traveling-carrier photodiodes (MUTC-PDs) providing a record high output power level for non-resonant photodiodes in the WR3.4 band. Indium phosphide (InP) based ... -
Photonic-assisted 2-D terahertz beam steering enabled by a LWA array monolithically integrated with a BFN
Haddad, Thomas; Biurrun Quel, Carlos ; Lu, Peng; Tebart, Jonas; Sievert, Benedikt; Makhlouf, Sumer; Grzeslo, Marcel; Teniente Vallinas, Jorge ; Río Bocio, Carlos del ; Stöhr, Andreas (Optica, 2022)
Artículo / Artikulua
A novel photonic-assisted 2-D Terahertz beam steering chip using only two tuning elements is presented. The chip is based on an array of three leaky wave antennas (LWAs) with a monolithically integrated beamforming network ... -
Suppressing open stopband for terahertz periodic microstrip leaky-wave antennas
Haddad, Thomas; Biurrun Quel, Carlos ; Lu, Peng; Kaya, Hacer; Mohammad, Israa; Stöhr, Andreas (IEEE, 2023)
Contribución a congreso / Biltzarrerako ekarpena
This paper reports on a periodic microstrip Leaky-wave antenna (LWA). The open stopband issue is suppressed by altering the unit cell using a matching stub. The developed LWA is based on a grounded InP-substrate of 50 ...
