Silicon nitride microwave photonic circuits.
Optics Express, 2013 We present an overview of several microwave photonic processing functionalities based on combinations of Mach-Zehnder and ring resonator filters using the high index contrast silicon nitride (TriPleX™) waveguide technology.

Photonic Integrated Circuits for Microwave Astronomy
Inventions, 2023 One of the main objectives of cosmology is the measurement of the Cosmic Microwave Background (CMB) polarization and, in particular, the so-called B-modes, which could demonstrate the existence of the primordial gravitational waves generated at the early

Universal Gate Set for Continuous-Variable Quantum Computation with Microwave Circuits. [PDF]
Physical Review Letters, 2020 We provide an explicit construction of a universal gate set for continuous-variable quantum computation with microwave circuits. Such a universal set has been first proposed in quantum-optical setups, but its experimental implementation has remained ...

Nonreciprocal Reconfigurable Microwave Optomechanical Circuit [PDF]
2018 International Conference on Optical MEMS and Nanophotonics (OMN), 2017 AbstractNonreciprocal microwave devices are ubiquitous in radar and radio communication and indispensable in the readout chains of superconducting quantum circuits. Since they commonly rely on ferrite materials requiring large magnetic fields that make them bulky and lossy, there has been significant interest in magnetic-field-free on-chip alternatives,

Electric circuit model of microwave optomechanics [PDF]
Journal of Applied Physics, 2021 We report on the generic classical electric circuit modeling that describes standard single-tone microwave optomechanics. Based on a parallel RLC circuit in which a mechanical oscillator acts as a movable capacitor, derivations of analytical expressions are presented, including key features such as the back-action force, the input–output expressions ...
