Linear Electro-optic Effect in Silicon Nitride Waveguides Enabled by Electric-Field Poling

Camille Sophie Brès, Anton Stroganov, Boris Zabelich, Edgars Nitiss

Stoichiometric silicon nitride (Si3N4) is one of the most mature integrated photonic platforms for linear and nonlinear optical applications on-chip. However, because it is a centrosymmetric material, second-order nonlinear processes are inherently not ava ...

Time-continuous Travelling-Wave Optical Parametric Amplification in a Photonic Circuit

Tobias Kippenberg, Rui Ning Wang, Nikolai Kuznetsov, Junqiu Liu, Jijun He

We demonstrate a traveling wave parametric amplifier in a photonic Si3N4 integrated spiral waveguide of 2.0 m length with footprint 3x5 mm. We achieve net gain of 7 dB on-chip and 2 dB fiberto-fiber in the optical C-band. (C) 2022 The Author(s) ...

Room-temperature electrical control of polarization and emission angle in a cavity-integrated 2D pulsed LED

Andras Kis, Fedele Tagarelli, Dmitrii Unuchek, Zhe Sun, Juan Francisco Gonzalez Marin, Cheol Yeon Cheon

Devices based on two-dimensional (2D) semiconductors hold promise for the realization of compact and versatile on-chip interconnects between electrical and optical signals. Although light emitting diodes (LEDs) are fundamental building blocks for integrate ...

Optically reconfigurable quasi-phase-matching in silicon nitride microresonators

Camille Sophie Brès, Jianqi Hu, Anton Stroganov, Edgars Nitiss

Quasi-phase-matching has long been a widely used approach in nonlinear photonics, enabling efficient parametric frequency conversions such as second-harmonic generation. However, in silicon photonics the task remains challenging, as materials best suited f ...

Electric-field poling of silicon nitride waveguides for the linear phase modulation

Camille Sophie Brès, Anton Stroganov, Boris Zabelich, Edgars Nitiss

Stoichiometric silicon nitride (Si3N4) constitutes a mature platform for integrated photonics. Its pertinent properties, including wide transparency window from the visible to the mid-IR, low propagation loss, and high third-order nonlinearity, are exploit ...

Magic-angle magnonic nanocavity in a magnetic moiré superlattice

Jean-Philippe Ansermet, Haiming Yu, Jilei Chen, Jianyu Zhang, Yao Zhang, Song Liu, Wenhao Jiang

Moiré superlattices have recently been extensively studied in both electronic and photonic systems, e.g., magic-angle bilayer graphene showing superconductivity and twisted bilayer photonic crystals leading to magic-angle lasers. However, the moiré physics ...

Backward Second-Harmonic Generation in Optically Poled Silicon Nitride Waveguides

Camille Sophie Brès, Jianqi Hu, Ozan Yakar, Edgars Nitiss

We report the inscription of quasi-phase-matching gratings in silicon nitride waveguides for backward second-harmonic-generation enabled by all-optical poling, therefore, circumventing the difficulties in inscribing poled domains with ultra-short periods. ...

Microwave-optical transduction with intergrated gallium phospide devices

Tobias Kippenberg, Alberto Beccari

Optomechanical resonators provide a route to interconversion of microwave and optical photons for quantum interconnects. We present a platform comprising a GaP photonic crystal cavity integrated on prefabricated niobium circuits, with mechanical modes at s ...

Spontaneous Brillouin Scattering in Gas-filled Anti-resonant Fibre

Luc Thévenaz, Malak Mohamed Hossameldeen Omar Mohamed Galal, Li Zhang, Suneetha Sebastian

Spontaneous Brillouin scattering is measured for the first time in a hollow-core anti-resonant fibre (HC-ARF) filled with Nitrogen (N2) gas at different pressures. A Brillouin gain of 0.029 m^−1W^−1 is yielded at a pressure of 34.7 bar. ...
