TL;DR: Experimental results on photonic crystal/photonic wire micro-cavity structures that demonstrate further enhancement of the quality-factor (Q-factor)--up to approximately 149,000--in the fibre telecommunications wavelength range are presented.

TL;DR: All-optical switching with a very low power is demonstrated on photonic crystal wire nano-cavities on silicon-on-insulator with large quality factors and high transmission in the telecom range.

TL;DR: In this article, a single-row photonic crystal (PhC) embedded in a 500nm-wide photonic wire waveguide was used to construct a microcavity that exhibits simultaneously high transmission and large resonance quality-factor.

TL;DR: In this article, the absorption characteristics of complex medium structures having metasurfaces comprised of columnar nanorods of gold were investigated, and the results showed that the absorber having elliptical gold nanors yields a better performance than the one with circular nanorod in terms of the magnitude/smoothness of the absorption peaks.

TL;DR: In this paper, the copper-graphene surface plasmon resonance (SPR)-based biosensor was investigated by considering the high adsorption efficiency of graphene, which is used to prevent Cu from oxidation and enhance the reflectance intensity.
