Fabrication of 1D and 2D vertical nanomagnetic resonators

چکیده
We have successfully fabricated the first resonant magnetic nanostructures exhibiting a negative permeability in the midinfrared. These metal-dielectric structures exhibit local resonances based on metallic inductive-capacitive effects that are controlled by the dimensions of the individual nanostructures and are independent of the periodicity, which is much smaller than the resonance wavelengths. Compared to other commonly used structures for obtaining negative permeability in the microwave and THz regions which are based on a planar fabrication paradigm, this structure is oriented vertically so that the smallest features are controlled by deposition rather than by lithography. © 2004 American Vacuum Society.

Design of photonic microcavities in hexagonal boron nitride
We propose and design photonic crystal cavities (PCCs) in hexagonal boron nitride (hBN) for diverse photonic and quantum applications. Two dimensional (2D) hBN flakes contain quantum emitters which are ultra-bright and photostable at room temperature. To achieve optimal coupling of these emitters to optical resonators, fabrication of cavities from hBN is therefore required to maximize the overl...

متن کاملVertically coupled microring resonators using one epitaxial growth step and single-side lithography.
A new concept for the fabrication of integrated microring resonators, requiring only one single epitaxial growth and two single-side lithographic steps, is proposed in what is the simplest fabrication scheme for vertical microrings published to date. The approach is based on two vertically stacked phase matched core layers. The effect of bus waveguide, coupling region and ring structure paramet...
متن کاملLow modal volume dipole-like dielectric slab resonator.
We propose a novel geometry in a silicon planar resonator with an ultra-small modal volume of 0.01(lambda/2n)(3). The geometry induces strong electric field discontinuities to decrease the modal volume of the cavity below 1(lambda/2n)(3) The proposed structure and other common resonators such as 1D and 2D photonic crystal resonators are compared for tradeoffs in confinement and quality factors.
