Kerr-optomechanical spectroscopy of multimode diamond resonators
Parisa Behjat, Peyman Parsa, Natalia C. Carvalho +2
Diamond microdisk cavities play a key role in optomechanical and spin-optomechanical technologies. Previous optomechanical studies of these devices have focused exclusively on thei…
Diamond Integrated Quantum Photonics: A Review
Prasoon K. Shandilya, Sigurd Flågan, Natalia C. Carvalho +4
Integrated quantum photonics devices in diamond have tremendous potential for many quantum applications, including long-distance quantum communication, quantum information processi…
Generation of Coherent Phonons via a Cavity Enhanced Photonic Lambda Scheme
Jeremy Bourhill, Natalia do Carmo Carvalho, Maxim Goryachev +2
We demonstrate the generation of coherent phonons in a quartz Bulk Acoustic Wave (BAW) resonator through the photoelastic properties of the crystal, via the coupling to a microwave…
Accurate modeling and characterization of photothermal forces in optomechanics
André G. Primo, Cauê M. Kersul, Rodrigo Benevides +6
Photothermal effects have been pointed out as prominent sources of forces in optomechanical systems, competing with the standard radiation pressure interactions. In this Article, w…
High-Frequency GaAs Optomechanical Bullseye Resonator
N. C. Carvalho, R. Benevides, M. Ménard +3
The integration of optomechanics and optoelectronics in a single device opens new possibilities for developing information technologies and exploring fundamental phenomena. Gallium…
Quasinormal-mode perturbation theory for dissipative and dispersive optomechanics
André G. Primo, Natália C. Carvalho, Cauê M. Kersul +3
Despite the several novel features arising from the dissipative optomechanical coupling, such effect remains vastly unexplored due to the lack of a simple formalism that captures n…
Piezo-optomechanical coupling of a 3D microwave resonator to a bulk acoustic wave crystalline resonator
N. C. Carvalho, J. Bourhill, M. Goryachev +2
We report the observation of coupling between a 3D microwave cavity mode and a bulk mechanical resonator mediated by piezoelectric and radiation pressure effects. The system is com…
Sensitivity Characterisation of a Parametric Transducer for Gravitational Wave Detection Through Optical Spring Effect
N. C. Carvalho, O. D. Aguiar, J. Bourhill +1
We present the characterisation of the most recent parametric transducers designed to enhance the Mario Schenberg Gravitational Wave Detector sensitivity. The transducer is compose…
Low-Temperature Microwave Properties of Biaxial YAlO3
N. C. Carvalho, M. Goryachev, J. Krupka +2
Low-loss crystals with defects due to paramagnetic or rare earth impurity ions is a major area of investigation for quantum hybrid systems at both optical and microwave frequencies…
Multi-mode technique for the determination of the biaxial Y2SiO5 permittivity tensor from 300 to 6 Kelvin
N. C. Carvalho, J-M. Le Floch, J. Krupka +1
The Y2SiO5 (YSO) crystal is a dielectric material with biaxial anisotropy with known values of refractive index at optical frequencies. It is a well-known rare-earth (RE) host mate…
Discovery of higher order reentrant modes by constructing a cylindrical symmetric ring and post cavity resonator
Y. Fan, Z. Zhang, N. C. Carvalho +3
Analysis of the properties of resonant modes in a reentrant cavity structure comprising of a post and a ring was undertaken and verified experimentally. In particular we show the e…
Rigorous analysis of highly tunable cylindrical Transverse Magnetic mode re-entrant cavities
J-M. Le Floch, Y. Fan, M. Aubourg +8
Cylindrical re-entrant cavities are unique three-dimensional structures that resonate with their electric and magnetic fields in separate parts of the cavity. To further understand…
