TLDR
It is demonstrated theoretically that the resonance frequencies of high-Q microcavities in two-dimensional photonic crystal membranes can be tuned over a wide range by introducing a subwavelength dielectric tip into the cavity mode by varying the lateral and vertical positions of the tip.Abstract:
We demonstrate theoretically that the resonance frequencies of high-Q microcavities in twodimensional photonic crystal membranes can be tuned over a wide range by introducing a subwavelength dielectric tip into the cavity mode. Three-dimensional finite-difference time-domain simulations show that by varying the lateral and vertical positions of the tip, it is possible to tune the resonator frequency without lowering the quality factor. Excellent agreement with a perturbative theory is obtained, showing that the tuning range is limited by the ratio of the cavity mode volume to the effective polarizability of the nanoperturber.read more

Light Interaction with Photonic and Plasmonic Resonances
TL;DR: The theory and applications of optical micro and nanoresonators are presented from the underlying concept of their natural resonances, the so-called quasi-normal modes (QNMs), the latter are the basic constituents governing the response of resonators as mentioned in this paper.

High- Q photonic nanocavity in a two-dimensional photonic crystal
TL;DR: A silicon-based two-dimensional photonic-crystal slab is used to fabricate a nanocavity with Q = 45,000 and V = 7.0 × 10-14 cm3; the value of Q/V is 10–100 times larger than in previous studies, underlying the realization that light should be confined gently in order to be confined strongly.
