High-speed 1.3-µm p-i-n GaNAsSb/GaAs waveguide photodetector

Malek Zegaoui, Z. Xu, N. Saadsaoud, Kianhuan Tan, Wan Khai Loke, Satrio Wicaksono, Soon Fatt Yoon, Christiane Legrand, Didier Decoster, Jean Chazelas

The authors report the demonstration of high-speed GaNAsSb/GaAs p-i-n waveguide photodetector grown by molecular beam epitaxy technique. A 0.4-μm-thick GaNAsSb core layer with 3.3% of N and 8% of Sb for detection wavelength over 1.3 μm is sandwiched by GaAs and AlGaAs cladding layers. The device…

Optically power supplied Gbit/s wireless hotspot using 1.55 µm THz photomixer and heterodyne detection at 200 GHz

Guillaume Ducournau, P. Szriftgiser, Denis Bacquet, Alexandre Beck, Tahsin Akalin, Emilien Peytavit, Mohammed Zaknoune, Jean-Francois Lampin

A wireless transmission system with a remote-supplied hotspot is demonstrated working up to gigabit data rates. The emission uses a 200 GHz carrier frequency, generated using an 1.55 µm photomixer composed of an unitravelling carrier photodiode monolithically integrated with a wide bandwidth…

(Multi)exciton dynamics and exciton polarizability in colloidal InAs quantum dots

Joep J. H. Pijpers, M.T.W. Milder, C. Delerue, Mischa Bonn

We report steady state and dynamic properties of (multi)excitons in InAs quantum dots using femtosecond time-resolved transient absorption and time-resolved terahertz spectroscopy. The polarizability of confined excitons in the ground state is found to be of the order of 104 Å3, increasing sharply…

Dual phononic and photonic band gaps in a periodic array of pillars deposited on a thin plate

Y. El Hassouani, C. Li, Yan Pennec, E.H. El Boudouti, H. Larabi, Abdellatif Akjouj, Olivier Bou Matar, V. Laude, N. Papanikolaou, A. Martinez, Bahram Djafari-Rouhani

We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the centered square lattice and the boron nitride (BN) lattice with two atoms per unit cell which include the simple square, triangular and…
