We propose an on-chip nano-horm-shaped metal-clad cavity. The proposed device is 0.8 µm in height-half the size of the previously reported devices— and achieves the quality factor of 1000 and effective volume of 0.31(λ/n)3.
We proposed a novel approach to confine light in a silica microfiber (MF) cavity using a lattice constant-varying nanohole array. In our simulation study, the MF cavity is integrated with the optimally designed nanostructure, and produces -factors as high as 7 × 10 in the near-infrared region. The mode volume of the cavity remains close to , a much smaller value than those previously...
We propose a new, simple way to engineer the radiation patterns of subwavelength-scale metallic semiconductor cavities for coupling light from a nanoscale metal cavity into integrated waveguides uni-/bi-directionally with efficiency up to ∼90%.
