Terahertz 3D bulk metamaterials with randomly dispersed split-ring resonators
Nanophotonics, 2022 While optical systems using terahertz wave are expected to achieve beneficial applications, at present, the materials of the optical elements that compose them must be selected from limited choices.

Effect of Diffraction on Wigner Distributions of Optical Fields and how to Use It in Optical Resonator Theory. III -- Ray Tracing in Resonators [PDF]
arXiv, 2022 The third part of the paper is devoted to ray tracing in optical resonators. The employed method for dealing with the issue uses the elliptical or hyperbolic rotations that Wigner distributions associated with optical fields undergo during propagation from one spherical mirror of a resonator to the other.

Tunable Germanium-on-Insulator Band-Stop Optical Filter Using Thermo-Optic Effect
IEEE Photonics Journal, 2020 We demonstrate a tunable band-stop optical filter on a germanium-on-insulator photonic platform operating at 1.95 μm wavelength. The band-stop filter is implemented using parallel-coupled microring resonators with the number of microring ...

Brillouin optomechanics in the quantum ground state
Physical Review Research, 2023 Bulk acoustic wave (BAW) resonators are attractive as intermediaries in a microwave-to-optical transducer, due to their long coherence times and controllable coupling to optical photons and superconducting qubits.

Efficient quantum microwave-to-optical conversion using electro-optic nanophotonic coupled-resonators [PDF]
Phys. Rev. A 96, 043808 (2017), 2017 We propose a low noise, triply-resonant, electro-optic (EO) scheme for quantum microwave-to-optical conversion based on coupled nanophotonics resonators integrated with a superconducting qubit. Our optical system features a split resonance - a doublet - with a tunable frequency splitting that matches the microwave resonance frequency of the ...

An optical equilibrium in lateral waveguide-resonator optical force [PDF]
, 2013 We consider the lateral optical force between resonator and waveguide, and study the possibility of an equilibrium that occurs solely from the optical force. We prove analytically that a single- resonance system cannot give such an equilibrium in resonator-waveguide force. We then show that two-resonance systems can provide such an equilibrium.

Resonant optical trapping of Janus nanoparticles in plasmonic nanoaperture [PDF]
, 2023 Controlled trapping of light absorbing nanoparticles with low-power optical tweezers is crucial for remote manipulation of small objects. This study takes advantage of the synergetic effects of tightly confined local fields of plasmonic nanoaperture, self-induced back-action of nanoparticles, and resonant optical trapping method to demonstrate enhanced
