Lithium tantalate photonic integrated circuits for volume manufacturing

Tobias Kippenberg, Mikhail Churaev, Xinru Ji, Zihan Li, Alisa Davydova, Junyin Zhang, Yang Chen, Xi Wang, Kai Huang

Electro-optical photonic integrated circuits (PICs) based on lithium niobate (LiNbO3) have demonstrated the vast capabilities of materials with a high Pockels coefficient1,2. They enable linear and high-speed modulators operating at complementary metal–oxi ...

Indoor Positioning System Based on Global Positioning System Signals with Down- and Up-Converters in 433 MHz ISM Band

Amir Mohsen Ahmadi Najafabadi, Abdulkadir Uzun

In this paper, an indoor positioning system using Global Positioning System (GPS) signals in the 433 MHz Industrial Scientific Medical (ISM) band is proposed, and an experimental demonstration of how the proposed system operates under both line-of-sight an ...

High accuracy GNSS based navigation in GEO

Pierre-André Farine, Cyril Botteron, Vincenzo Capuano, Paul David Blunt, Endrit Shehaj

Although significant improvements in efficiency and performance of communication satellites have been achieved in the past decades, it is expected that the demand for new platforms in Geostationary Orbit (GEO) and for the On-Orbit Servicing (OOS) on the ex ...

Full C and L-Band Transmission at 20 Tbit/s Using Cavity-Soliton Kerr Frequency Combs

Tobias Kippenberg, Victor Brasch, Maxim Karpov, Arne Kordts, Mirjam Pfeiffer

Temporal soliton formation in a Kerr-nonlinear optical micro-resonator leads to a coherent frequency comb covering the C and L-band. We demonstrate WDM transmission with 94 comb lines and an aggregate data rate of 20 Tbit/s. ...

Lens-based Ka-band antenna system using planar feed

Juan Ramon Mosig, Marc Esquius Morote, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva

This paper presents a simple, low-cost and compact mobile ground terminal antenna for Ka-band satellite communications that operates in the downlink band (19.7-20.2 GHz). The antenna is composed of a shaped dielectric lens which tilts in front of a planar ...

Broadly tunable source around 2050 nm based on wideband parametric conversion and thulium–holmium amplification cascade

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette

We report the design of a short-wave infrared continuous-wave light source featuring a 20 mW average output power, and with a wavelength that can be freely selected in the 2000-2100 nm range amid a low power ripple. The operating principle relies on the si ...

A superconducting diplexer for cosmic microwave background experiments

Juan Ramon Mosig, Mohammadreza Madi, Michael Mattes

Cosmic microwave background (CMB) studies require observations in several frequency bands simultaneously. For example, the detection of clusters of remote galaxies can be performed by comparing CMB photon fluxes at different frequencies, using the spectral ...
