Momentum space design of high-Q photonic crystal optical cavities.
The design of high quality factor (Q) optical cavities in two dimensional photonic crystal (PC) slab waveguides based upon a momentum space picture is presented. The results of a symmetry analysis of defect modes in hexagonal and square host photonic lattices are used to determine cavity geometries that produce modes which by their very symmetry reduce the vertical radiation loss from the PC sl...
متن کاملImprovement of Optical Properties in Hexagonal Index-guiding Photonic Crystal Fiber for Optical Communications
Waveguides with low confinement loss, low chromatic dispersion, and low nonlinear effects are used in optical communication systems. Optical fibers can also be employed in such systems. Besides optical fibers, photonic crystal fibers are also highly suitable transmission media for optical communication systems. In this paper, we introduce two new designs of index-guiding photonic crystal fiber ...
متن کاملResonant optical trapping in microfluidic-integrated hollow photonic crystal cavities
The recent years have highlighted the potential of photonic nanostructures to extend the capabilities of optical tweezers and to perform advanced optical manipulations. In this context, two-dimensional photonic crystal cavities have been regarded as promising candidates owing to their high quality factors and low mode volumes. The work presented in this thesis reports the setting up of a comple...
متن کاملDesign of Photonic Crystal Cavities for Extreme Light Concentration
The fields of photonic crystals and plasmonics have taken two different approaches to increasing light−matter interaction. Photonic crystal cavities increase temporal confinement of light in a material, as represented by their high quality factor, while plasmonic structures increase spatial confinement, as represented by their low mode volume. However, the inability to simultaneously attain ext...
متن کاملDesign of nano-groove photonic crystal cavities in lithium niobate.
We propose a novel design of photonic-crystal nanobeam cavities in lithium niobate (LN) for both TE and TM modes, addressing problems associated with tilted sidewalls, which commonly result from dry etching. Using optimized periodical nano-groove structures, the proposed devices could achieve quality factors as high as 3.9×10(6) with a modal volume of 5.0 (λ/n)3. We also show that such a design...
