Integrated horn antenna for THz photomixing in LTG-GaAs

Emilien Peytavit, Jean-Francois Lampin, Tahsin Akalin, Francis Mollot, Francis Hindle, Chun Yang, Gaël Mouret

The investigation of THz generation using low-temperature-grown GaAs (LTG-GaAs) photoconductors integrated with horn antennas is reported. Results obtained using a photomixing experiment are presented. A maximum generated power of 1 muW at 780 GHz was achieved for an optical power of 2times80 mW…

New developments on diamond photodetector for VUV solar observations

Ali Benmoussa, Ali Soltani, Ken Haenen, Udo Kroth, Vincent Mortet, Hassan Ali Barkad, David Bolsée, Christian Hermans, M. Richter, Jean-Claude de Jaeger, Jean-François Hochedez

A new large-size metal–semiconductor–metal photoconductor device of 4.6 mm in diameter based on diamond material has been reprocessed and characterized in the vacuum-ultraviolet (VUV) wavelength range. The metal finger contacts have been processed to 2 µm in width with spacing between the contacts…

1.55 µm GaAs/GaNAsSb/GaAs optical waveguides grown by radio frequency nitrogen plasma-assisted molecular beam epitaxy

Kianhuan Tan, Soon Fatt Yoon, Wan Khai Loke, Satrio Wicaksono, Zhichuan Xu, Tien Khee Ng, Kim Luong Lew, N. Saadsaoud, Malek Zegaoui, Didier Decoster, Jean Chazelas

We demonstrate a 1.55 μm GaAsGaNAsSbGaAs optical waveguide grown by molecular beam epitaxy as an alternative to the AlGaAsGaAs system. The 0.4-μm -thick GaNAsSb guiding layer contains ∼3.5% of N and 9% of Sb, resulting in optical band gap of 0.88 eV. The refractive index of the GaNAsSb layer was…
