The mode structure of microcrystal and microdroplet lasers
The work horse of optics is the ray picture – i.e., the short-wavelength limit of Maxwell’s wave equations. In the form of the paraxial approximation, it is also the backbone of conventional optical resonator theory. Without such approximations, one is forced to resort to numerical solutions of the full wave equations, which in general reduces resonator design to trial-and-error. An exception a...
متن کاملCavity resonators of metal-coated dielectric nanorods.
Metallic nanoparticles bridge the length scale between atoms and crystals, exhibiting mesoscopic properties unique to their size. Thus, they have generated much interest for their potential applications as chemical or biological sensors and particularly as waveguides for light in nanoscale structures. [Y. W. C. Cao, R. C. Jin, and C. A. Mirkin, Science 297, 1536 (2002); H. J. Lezec et al., Scie...
متن کاملDielectric-loaded plasmonic waveguide-ring resonators.
Using near-field microscopy, the performance of dielectric-loaded plasmonic waveguide-ring resonators (WRRs) operating at telecom wavelengths is investigated for various waveguide-ring separations. It is demonstrated that compact (footprint approximately 150 microm(2)) and efficient (extinction ratio approximately 13 dB) WRR-based filters can be realized using UV-lithography. The WRR wavelength...
متن کاملTunable Channel Drop Filter using Hexagonal Photonic Crystal Ring Resonators
In this paper, we have proposed a tunable two dimensional (2D) photonic crystal (PhC) channel drop filter (CDF) using ring resonators with suitable quality factor (Q) and transmission efficiency; we investigate parameters which have an effect on resonant wavelength in this CDF, such as dielectric constant of inner, coupling, adjacent and whole rods of the structure. Dropping efficiency at the r...
متن کاملNanophotonic biosensors using hexagonal nanoring resonators: computational study
Chengkuo Lee National University of Singapore Department of Electrical and Computer Engineering 4 Engineering Drive 3 Singapore, Singapore 117576 E-mail: elelc@nus.edu.sg Abstract. The characteristics of biochemical sensors based on photonic crystal (PC) resonators are investigated in this work. The PC structure consists of holes arranged in a hexagonal lattice on a silicon slab. The nanoring r...
