TL;DR: In this paper, the results of two-photon study of CdTe quantum dots (QDs) in chloroform were presented, and the measured 2PA coefficient at ∼1300nm is ∼0.02cm∕GW.
Abstract: This letter presents the results of two-photon study of CdTe quantum dots (QDs) in chloroform. The measured two-photon absorption (2PA) spectrum shows that 2PA coefficient at ∼1300nm is ∼0.02cm∕GW. Based on a 1cm path-length CdTe QD solution sample of 8mg∕ml concentration, irradiated by a focused ∼1300nm laser beam of ∼160fs duration, the nonlinear transmission could be changed from ∼100% to ∼20% when the input pulse energy was varied from ∼50nJto∼10μJ, demonstrating a superior optical limiting performance. The input laser fluctuation was significantly reduced after passing through the sample, indicating a remarkable optical stabilization behavior.

TL;DR: In this paper, a two-dimensional frequency domain model for circular integrated optical (ring or disk) micro-resonators based on spatial coupled mode theory is proposed. But the spectral response and field examples for the micro-reonators with mono-and multi-modal cavities for TE and TM polarizations are presented.

TL;DR: In this paper, the authors demonstrate the controlled assembly of such hybrid structures via manipulation with scanning near-field probes, and investigate the plasmonic enhancement of the single photon emission through coupling to gold nanospheres as well as the coupling of diamond nanocrystals to the optical modes of microsphere resonators and photonic crystal cavities.

TL;DR: This work presents the first scaled microcavity system which enables the creation of large numbers of highly uniform, tunable light-matter interfaces using ions, neutral atoms or solid-state qubits.
Abstract: Optical cavities are of central importance in numerous areas of physics, including precision measurement, cavity optomechanics and cavity quantum electrodynamics. The miniaturisation and scaling to large numbers of sites is of interest for many of these applications, in particular for quantum computation and simulation. Here we present the first scaled microcavity system which enables the creation of large numbers of highly uniform, tunable light-matter interfaces using ions, neutral atoms or solid-state qubits. The microcavities are created by means of silicon micro-fabrication, are coupled directly to optical fibres and can be independently tuned to the chosen frequency, paving the way for arbitrarily large networks of optical microcavities.

TL;DR: In this article, the effect of various geometrical parameters on the resonator performance is investigated in detail, and the characteristic electric field patterns that occur at major and minor resonance wavelengths are investigated.
Abstract: Two dielectric waveguides that are evanescently coupled to a square or rectangular region of increased refractive index can serve as a very compact integrated optical microresonator. We consider these devices in a spatial two-dimensional setting, where a rigorous mode expansion technique enables accurate and quite efficient numerical simulations of these configurations. The paper is concerned with single resonator units as well as with an add-drop filter constructed by cascading two square cavities. Besides calculating the power transmission spectra, we try to document as far as possible the characteristic electric field patterns that occur at major and minor resonance wavelengths. The influence of the various geometrical parameters on the resonator performance is investigated in detail.
