| 1 | New acoustic system for continuous measurement of river discharge and water temperature显示文摘In many cases,river discharge is indirectly estimated from water level or streamflow velocity near the water surface.However,these methods have limited applicability.In this study,an innovative system,the fluvial acoustic tomography system(FATS),was used for continuous discharge measurement.Transducers with a central frequency of 30 kHz were installed diagonally across the river.The system's significant functions include accurate measurement of the travel time of the transmission signal using a GPS clock and the attainment of a high signal-to-noise ratio as a result of modulation of the signal by the 10th order M-sequence.In addition,FATS is small and lightweight,and its power consumption is low.Operating in unsteady streamflow,FATS successfully measured the cross-sectional average velocity.The agreement between FATS and acoustic Doppler current profilers(ADCPs) on water discharge was satisfactory.Moreover,the temporal variation of the cross-sectional average temperature deduced from the sound speed of FATS was similar to that measured by a temperature sensor near the bank. | Kiyosi KAWANISI Arata KANEKO Shinya NIGO Mohammad SOLTANIASL Mahmoud F.

| 2 | Ultra-broadband nanophotonic phase shifter based on subwavelength metamaterial waveguides显示文摘Optical phase shifters are extensively used in integrated optics not only for telecom and datacom applications but also for sensors and quantum computing.While various active solutions have been demonstrated,progress in passive phase shifters is still lacking.Here we present a new type of ultra-broadband 90°phase shifter,which exploits the anisotropy and dispersion engineering in subwavelength metamaterial waveguides.Our Floquet–Bloch calculations predict a phase-shift error below 1.7°over an unprecedented operation range from 1.35 to 1.75μm,i.e.,400 nm bandwidth covering the E,S,C,L,and U telecommunication bands.The flat spectral response of our phase shifter is maintained even in the presence of fabrication errors up to 20 nm,showing greater robustness than conventional structures.Our device was experimentally demonstrated using standard220 nm thick SOI wafers,showing a fourfold reduction in the phase variation compared to conventional phase shifters within the 145 nm wavelength range of our measurement setup.The proposed subwavelength engineered phase shifter paves the way for novel photonic integrated circuits with an ultra-broadband performance. | DAVID GONZáLEZ-ANDRADE JOSéMANUEL LUQUE-GONZáLEZ J.GONZALO WANGüEMERT-PéREZ ALEJANDRO ORTEGA-MONUX PAVEL CHEBEN íNIGO MOLINA-FERNáNDEZ AITOR V.VELASCO | 2020 | Photonics Research2020，8，3： | 2 |
