Modeling of grating assisted standing wave microresonators for filter applications in integrated optics

A wide, multimode segment of a dielectric optical waveguide, enclosed by Bragg reflectors and evanescently coupled to adjacent port waveguides, can constitute the cavity in an integrated optical microresonator. It turns out that the device can be described adequately in terms of an approximate coupled mode theory model which involves only a few guided modes as basis fields. By reasoning along the coupled mode model, we motivate a simple design strategy for the resonator device. Rigorous two dimensional mode expansion simulations are applied to verify the predictions of the approximate model. The results exemplify the specific spectral response of the standing wave resonators. As refinements we discuss the single resonance of a device with nonsymmetrically detuned Bragg reflectors, and the cascading of two Fabry-Perot cavities, where the coupling across an intermediate shorter grating region establishes a power transfer characteristic that is suitable for an add-drop filter

A study of slow light in 1D photonic crystals

Slow light (SL) states corresponding to wavelength regions near the bandgap edge of grating structure are known to show strong field enhancement. Such states may be excited efficiently by well-optimised adiabatic transitions in such structures, e.g., by slowly turning on the modulation depth. To study adiabatic excitations, a detailed research in 1D is performed to obtain insight into the relation between the device parameters and properties like enhancement and modal reflection. The results enable the design of an adiabatic device for efficient excitation of SL states in 1D. In addition of that, the effects of small wavelength variations as well as that of small fluctuations in the modulation depth of the grating have been investigated

Comparison of neutrophil lymphocyte ratio (NLR), mean platelet volume (MPV) and platelet lymphocyte ratio (PLR) in preeclampsia and normotensive pregnancies

The study aimed to compare the NLR (neutrophil lymphocyte ratio), MPV (meanplatelet volume), and PLR (platelet lymphocyte ratio) values in preeclampsiaand normotensive pregnancies. This was a retrospective case-control studyusing medical records of pregnancies between January 1, – December 31, 2019.A total 31 pregnancies with preeclampsia who met the inclusion and exclusioncriteria were involved in the study. As control, 31 normotensive pregnanciesrecruited by simple random sampling were used. The data were presented asmean ± standard deviation (SD) and analyzed by using SPSS program. Receiveroperating characteristic (ROC) curve were used to determine the optimal cutoff point for predicting preeclampsia. The NLR and MPV values of patients withpreeclampsia were significantly higher compare to normotensive pregnancy(p0.245). The result of AUC analysis showed that the NLR and MPVhave AUC values of 0.758 (95%CI:0.637-0.878; p=0.000) and 0.903 (95%CI:0.816-0.989; p=0.000), respectively. Further analysis showed that the optimal cut-offpoint for NLR was 4.0 (sensitivity of 64.5% and a specificity of 71.0%) and forMPV was 7.55 (sensitivity of 87.1% and specificity of 80.0%). In conclusion, theNLR and MPV values are significantly higher in preeclampsia. However, theMPV value has a better predictive value than NLR for preeclampsia

Simulation of Electric Field Distribution on Meniscus of Electrospray with Zinc Oxide Material

Electrospray system had attracted attention of many researchers. It is due to easy to yield uniform thin film and possible for thin film mass production. The important parameters of electrospray process for getting uniform thin film are electric field distribution, surface substrate treatment and solvent properties. In this work, we observed electric field distribution on meniscus. Numerical work has carried out on this work. The material on meniscus used zinc oxide liquid properties. Voltage and walking distance between nozzle and substrate are the most important parameter to adjust electric field distribution. The decreasing walking distance with constant voltage yields increasing electric field distribution on meniscus. On vice versa, the increasing walking distance yields decreasing electric field distribution on meniscus. Increasing and decreasing voltage yields increasing and decreasing electric field distribution on meniscus, respectively
