Abstract

We demonstrate a free-space amplitude modulator for mid-infrared radiation (lambda=9.6 um) that operates at room temperature up to at least 20 GHz (above the -3dB cutoff frequency measured at 8.2 GHz). The device relies on the ultra-fast transition between weak and strong-coupling regimes induced by the variation of the applied bias voltage. Such transition induces a modulation of the device reflectivity. It is made of a semiconductor heterostructure enclosed in a judiciously designed array of metal-metal optical resonators, that - all-together - behave as an electrically tunable surface. At negative bias, it operates in the weak light-matter coupling regime. Upon application of an appropriate positive bias, the quantum wells populate with electrons and the device transitions to the strong-coupling regime. The modulator transmission keeps linear with input RF power in the 0dBm - 9dBm range. The increase of optical powers up to 25 mW exhibit a weak beginning saturation a little bit below.

Abstract

Thanks to intrinsically short electronic relaxation on the ps time scale, III-V semiconductor unipolar devices are ideal candidates for ultrahigh-speed operation at mid-infrared frequencies. In this work, antenna-coupled, GaAs-based multi quantum-well photodetectors operating in the 10-11um range are demonstrated, with a responsivity of 0.3A/W and a 3dB-cutoff bandwidth of 100GHz at room-temperature. The frequency response is measured up to 220GHz: beyond 100GHz we find a roll-off dominated by the 2.5 ps-long recombination time of the photo-excited electrons. The potential of the detectors is illustrated by setting up an experiment where the time dependent emission frequency of a quantum cascade laser operated in pulsed mode is measured electronically and in real-time, over a frequency range >60GHz. By exploiting broadband electronics, and thanks to its high signal-to-noise ratio, this technique allows the acquisition, in a single-shot, of frequency-calibrated, mid-infrared molecular spectra spanning up to 100GHz and beyond, which is particularly attractive for fast, active remote sensing applications in fields such as environmental or combustion monitoring.

Abstract

Images of the steady-state luminescence of passivated GaAs self-standing films under excitation by a tightly-focussed laser are analyzed as a function of light excitation power. While unipolar diffusion of photoelectrons is dominant at very low light excitation power, an increased power results in a decrease of the diffusion constant near the center of the image due to the onset of ambipolar diffusion. The results are in agreement with a numerical solution of the diffusion equations and with a physical analysis of the luminescence intensity at the centre of the image, which permits the determination of the ambipolar diffusion constant as a function of electron concentration., Comment: 5 figures

9. Terahertz Communication: A Story of Bandwidth and Silicon Photonic Integration

Abstract

The need for faster wireless data is ever-increasing. This puts pressure on the radio spectrum as most sub-6 GHz bands are already congested. Moving to higher bands, in the mmWave and Terahertz (THz) spectrum, unlocks large ranges of bandwidth. At these THz frequencies, however, high-gain directive beams are needed to compensate the higher path loss. Phased Antenna Arrays (PAA) provide this gain but need efficient beamforming feeding networks. In contrast to all-electrical approaches, an optical beamforming network (OBFN) is able to scale to large planar arrays. This is thanks to its small-footprint – as the radio signals are modulated on an optical carrier with a much smaller waveguide - and low-loss waveguides in Silicon Photonic (SiPh) platforms - feeding every individual antenna element. Generating THz signals is then only limited by the efficiency of the photomixer, i.e. a photodetector that converts the beat note of two optical signals to a THz signal. To this end, we have integrated a photodiode with a bandwidth of 155 GHz on a Silicon Nitride (SiN) waveguide and demonstrated its capabilities in a back-to-back THz link at 280 GHz. Doing so, we achieved data rates beyond 100 Gbit/s.

Abstract

International audience; Silicon-nitride-based integrated photonic platforms currently lack fast photodiodes, limiting its adoption for high-speed optical transceivers. We show uni-traveling-carrier (UTC) photodiodes heterogeneously integrated by means of micro-transfer-printing and demonstrate their excellent bandwidth performance at 1550 nm, achieving net bit rates in excess of 350 Gbit/s.

Abstract

Renatech Network; International audience; In this article, we present a 300-GHz wireless link composed of a photonic uni-traveling-carrier diode transmitter and an active electronic receiver based on millimeter wave integrated circuits fabricated in an InGaAs metamorphic high electron mobility transistor technology. The input pseudorandom binary sequence is transmitted and analyzed offline using fast analog-to-digital converters. The data transmission reaches ,100 Gb/s over a distance of 15 m. Complex modulation formats, such as 32-quadrature amplitude modulation and 64-quadrature amplitude modulation, are successfully transmitted up to a symbol rate of 8 GBd. The system presents not only high linearity but is also capable of transmitting high symbol rates, up to 40 GBd. To the best of the authors' knowledge, this represents the highest ever reported transmission bandwidth as well as the highest spectral density symbol rate product for transmissions with center frequency in the terahertz band. Thus, the usage of such links in future bandwidth-hungry applications, such as data centers, data showers, fronthaul, and backhaul, is proven feasible.

Abstract

National audience; Nous avons conçu et construit un système optique de synthèse d’ondes hyperfréquences, millimétriques et submillimétriques à très bas bruit de phase. Les résultats préliminaires montrent une densité spectrale de bruit de phase à 10 kHz de la porteuse d’une onde à 9 GHz limitée par l’appareil de mesure. Pour les bruits plus près de la porteuse, le bruit de phase est limité par une modulation d’amplitude résiduelle : le système est en cours de modifications.

Abstract

In this paper, we demonstrate a new technique to realize TiN/Ni nanodots array on silicon substrate using e-beam lithography and dry etching techniques. After patterning the Ni nanodisk (7 nm thick, 150 nm in diameter) at perfectly controlled location, individual vertically aligned carbon nanotubes (VACNTs) were grown using plasma-enhanced chemical-vapor deposition (PECVD). In addition, a field emission cathode (1 mm diameter circular emission area) based on a hexagonal array (20μm spacing) of individual VACNTs delivered a high emission current of 4.23 mA for an applied electric field of 22.5V/μm.

Abstract

We present in this paper spectral and spatial characteristics of terahertz emission from standard dipole antenna structures used as emitters depending on the substrate material. All antenna structures were lithographically fabricated on low-temperature (LT) grown, few-micrometers-thick gallium arsenide (GaAs) layers. To investigate the effect of the substrate material on the radiation pattern of terahertz beams, either semi-insulating gallium arsenide or high-resistivity silicon substrate wafers have been used. As detector a standard 40 µm long dipole antenna on a semi-insulating GaAs substrate with a low-temperature grown gallium arsenide layer on it has been employed; this configuration allows for broadband detection and is still efficient enough for the characterization purpose. Strong dependence of the radiation pattern on the substrate used for the terahertz source is demonstrated. The measured patterns and differences between the two cases of substrates are well explained by means of classical diffraction.

Abstract

A narrowband terahertz signal generated by a uni-travelling carrier photodiode (UTC-PD) interfaced with a dual-mode Fabry-Pérot laser diode is demonstrated. A beat tone corresponding to the free spectral range is generated on the UTC-PD, and radiated by a transverse-electromagnetic-horn antenna. All components involved in this experiment operate at room temperature. The terahertz signal at a frequency of 372 GHz is recorded, and the linewidth is 17 MHz. The linewidth and the tunability of the emitted terahertz wave are analyzed, as a function of the laser bias.
