Integrated optical gyroscope using active long-range surface plasmon-polariton waveguide resonator.

Optical gyroscopes with high sensitivity are important rotation sensors for inertial navigation systems. Here, we present the concept of integrated resonant optical gyroscope constructed by active long-range surface plasmon-polariton (LRSPP) waveguide resonator. In this gyroscope, LRSPP waveguide doped gain medium is pumped to compensate the propagation loss, which has lower pump noise than that of conventional optical waveguide.

Role of bone marrow-derived mesenchymal stem cells in a rat model of severe acute pancreatitis.

Aim: To investigate the role and potential mechanisms of bone marrow mesenchymal stem cells (MSCs) in severe acute peritonitis (SAP).

Methods: Pancreatic acinar cells from Sprague Dawley rats were randomly divided into three groups: non-sodium deoxycholate (SDOC) group (non-SODC group), SDOC group, and a MSCs intervention group (i.e.

Tunable microring resonator based on dielectric-loaded surface plasmon polariton waveguides.

Integrated optical ring resonators are essential elemental components for integrated optical circuits. An ultrasmall thermo-optical microring resonator with two bus waveguide-configuration based on surface plasmon polariton waveguide is theoretically analyzed. The thermo-optical coefficient, the temperature-dependent amplitude attenuation coefficient and the temperature distribution properties of the waveguide are investigated numerically by finite element method.

Vascular exclusion by preserving tumor-contralateral branch of hepatic artery in hepatectomy in treatment liver cancer with cirrhosis.

Background/aims: To investigate the effectiveness and safety of vascular exclusion by preserving tumor-contralateral branch of hepatic artery in hepatectomy in treatment liver cancer with cirrhosis.

Methodology: The clinical data of 10 cases treated with hepatectomy for liver cancer were analyzed retrospectively. Vascular exclusion by preserving tumor-contralateral branch of hepatic artery was applied to control bleeding.

Self-assembly of large-scale and ultrathin silver nanoplate films with tunable plasmon resonance properties.

We describe a rapid, simple, room-temperature technique for the production of large-scale metallic thin films with tunable plasmonic properties assembled from size-selected silver nanoplates (SNPs). We outline the properties of a series of ultrathin monolayer metallic films (8-20 nm) self-assembled on glass substrates in which the localized surface plasmon resonance can be tuned over a range from 500 to 800 nm. It is found that the resonance peaks of the films are strongly dependent on the size of the nanoplates and the refractive index of the surrounding dielectric.

Numerical analysis of deep sub-wavelength integrated plasmonic devices based on Semiconductor-Insulator-Metal strip waveguides.

We report the first study of nanoscale integrated photonic devices constructed with semiconductor-insulator-metal strip (SIMS) waveguides for use at telecom wavelengths. These waveguides support hybrid plasmonic modes transmitting through a 5-nm thick insulating region with a normalized intensity of 200-300 μm(-2). Their fundamental mode, unique transmission and dispersion properties are consistent with photonic devices for guiding and routing of signals in communication applications.
