An efficient advanced numerical model for mapping the distribution of buried tree roots is presented. It not only simplify complicate root branches to an easy manipulated model, but also grasp main structure ignoring unnecessary minutiae, and thus provide intuitive impression subsurface invisible anomalies. The processing combined with adaptive finite element method, which can automatically generate unstructured triangular meshes during process discretization, enable user specifically set...
Optical voltage sensors based on reflection interferometry of two orthogonal polarizations have been demonstrated by using a polymeric integrated optic device, in which thermooptic phase modulator, polarization converter, and polarizer are single chip. The sensing probe for electric field measurement was prepared assembling an LiTaO <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sub> electrooptic crystal along with maintaining collimator,...
The paper introduces a 24-channel air-trench isolated Silica-based VOA array. air trenches thermally insulate the VOAs with etched-free waveguide technologies. Reactive ion etching and wet were used at different channel locations to suppress thermal crosstalk reduce power consumption. When is declined by 3 dB for straight waveguide, consumption was decreased from 195 95 mW because lightwave radiation can be scattered trench in dark state. This improved 9 curved waveguide. polarization...
The paper introduces a silica-on-silicon monolithic integrated cyclic arrayed waveguide grating (AWG) with Mach-Zehnder interference (MZI) filters and vertical reflecting mirrors in silicon to realize effective stable optical transmission between waveguides photodiodes. AWG acts as both multiplexer over the L-band for upstream traffic demultiplexer C-band downstream traffic. chip, including AWG, MZI filters, mirrors, has been made successfully 6.0 dB insertion loss, which is less than...
The uncooled IR thermal imaging technology with its wide applications in military, medical and industrial areas has been an active topic international research. Thermal based on optical readout bi-material microcantilever array is a new concept methodology. In this paper, kind of micro-cantilever unit multi-fold legs interval gild structure designed thermo-mechanical performance are analylized. A 100×100 fabricated as FPA (focal plane array), by using FPA, image room-temperature body (human...
In this paper, a unique device that can act as both multiplexer and demultiplexer is proposed with two all-metal compensating rods makes the compensated chip almost same spectrum profile original one. way flat-top athermal arrayed-waveguide grating module of 100-GHz×40-ch successfully fabricated. A small center wavelength shift ±25 pm achieved for ultra-wide temperature range from -40°C to 85°C low insertion loss change less than ±0.14 dB.

光镊技术被广泛应用在俘获和操纵微纳米尺寸颗粒, 目前被研究学者普遍接受的俘获吸光性颗粒的机理为光泳力. 本文实现了对空气中被俘获的吸光性颗粒的红外显微观测. 当激光器功率为1.0 W时, 成功观测到被俘获墨粉颗粒(直径约7 μm)和甲苯胺蓝颗粒(直径约为1–20 μm)的温升约为14 K, 为光泳力理论提供了强有力的证据. 另外, 首次用可见光显微镜和红外显微镜同时观测到被俘获颗粒的周期振荡现象, 并分析了振荡现象的产生机理.
Technology transfer is deeply embedded in the WTO Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS Agreement). Several provisions address technology transfer, which constitute an essential part efforts made by TRIPS negotiators to strike a balance between advancement technological innovation and promotion dissemination technology. Article 66.2 specifically obligates developed country Members provide incentives enterprises institutions their territories promote...
An optical passband filter based on transmission liquid crystal technology is proposed and demonstrated. The bandwidth, wavelength attenuation can be tuned by controlling the voltage applied chips. insertion loss <3dB, bandwidth tunable range from 50GHz to 5000GHz, 0 15dB. meet technical requirements of CDCF ROADM.
The paper introduces a low crosstalk and power consumption dark 24ch-VOA Array based on Silica-on-Silicon, with thermally-insulating trenches etched-free waveguides technologies in different channels, the IL PDL are lower at 15dB attenuation.
We theoretically and experimentally report a single-wavelength module of 1x4 wavelength selective switch (WSS) based on the bi-axial MEMS mirror thin film filter technology.
