28 Jun 2001TL;DR: In this paper, a miniaturized chemical sensor features an optical microcavity (12) coated with a surface layer (14), and a waveguide (18) that evanescently couples light into the micro cavity.
Abstract: A miniaturized chemical sensor features an optical microcavity (12) coated with a surface layer (14), and a waveguide (18) that evanescently couples light into the microcavity (12) The surface layer (14) is adapted to chemically interact with one or more molecule species in a chemical vapor surrounding the microcavity (12), so as to alter the evanescent light The chemical interaction causes a change in the index of refraction of the microcavity (12), resulting in a measurable phase different readout The refractive index sensitivity is substantially increased because of the high Q-value of the optical microcavity (12)

TL;DR: An optical analogue of a quantum particle bouncing on a hard surface under the influence of gravity (a quantum bouncer) is experimentally demonstrated using a circularly curved optical waveguide.
Abstract: An optical analogue of a quantum particle bouncing on a hard surface under the influence of gravity (a quantum bouncer) is experimentally demonstrated using a circularly curved optical waveguide. Spatially resolved tunneling optical microscopy measurements of multiple beam reflections at the waveguide edge clearly show the appearance of wave packet collapses and revivals (either integer and fractional), corresponding to the full quantum regime of the quantum bouncer.

TL;DR: In this article, a protocol for conditional quantum logic between two four-state atoms inside a high-Q$ optical cavity is proposed, which utilizes a direct four-photon two-atom resonant process.
Abstract: We propose a protocol for conditional quantum logic between two four-state atoms inside a high-$Q$ optical cavity. The process detailed in this paper utilizes a direct four-photon two-atom resonant process and has the added advantage of commonly addressing the two atoms when they are inside the high-$Q$ optical cavity.

TL;DR: In this article, a T-shaped all-optical switch based on nonlinear photonic crystal microring resonator has been analyzed by the finite difference time domain method.
Abstract: A T-shaped all-optical switch based on nonlinear photonic crystal microring resonator has been analyzed by the finite difference time domain method. Photonic crystal microring resonators are used because they can enhance the nonlinearity due to the localization of light and slow group velocity. By cascading two of these switches we have shown the performance of a NOR gate. The simulations show that in the OFF state the transmission of the proposed NOR gate is only about 2% while in the ON state it is about 81%.
