名稱Anti-glare LED lamps with adjustable illumination light field
年度2014
類別期刊論文
摘要We introduce a type of LED light-gauge steel frame lamp with an adjustable illumination light field that does not require a diffusion plate. Base on the Monte Carlo ray tracing method, this lamp has a good glare rating (GR) of 17.5 at 3050 lm. Compared with the traditional LED lightgauge steel frame lamp (without diffusion plate), the new type has low GR. The adjustability of the illumination light field could improve the zebra effect caused by the inadequate illumination light field of the lamp. Meanwhile, we adopt the retinal image analysis to discuss the influence of GR on vision. High GR could reflect stray light on the retinal image, which will reduce vision clarity and hasten the feeling of eye fatigue.

名稱Ultracompact polarization rotator in an asymmetric single dielectric loaded rib waveguide
年度2016
類別期刊論文
摘要A compact polarization rotator (PR) with an asymmetric single dielectric loaded rib waveguide is proposed. The core of the waveguide is designed to have a specific rectangular configuration. The waveguide requires only a single asymmetrical dielectric loading on the core to complete the polarization conversion. The optical field is confined to the vicinity of the core center, which matches the optical field of the input/output waveguides. The transition loss of the PR is as low as 0.03–0.21 dB/facet without the taper or offset schemes. Such results can facilitate the fabrication of a PR with an operating length of 10 um. In a comprehensively designed PR with a length of 7.92 um, a –1 dB bandwidth for polarization conversion efficiency (PCE) is greater than 100 nm at the communicating wavelength of 1550 nm. The loading width and thickness with 20 nm tolerance exhibit −0.87 and −0.49 dB changes in PCE, respectively.

名稱8.13 um in length and CMOS compatible polarization beam splitter based on an asymmetrical directional coupler
年度2016
類別期刊論文
摘要A compact silicon polarization beam splitter (PBS) is proposed based on an asymmetrical directional coupler consisting of a wide waveguide and a dielectric loaded narrow waveguide. Given that TE and TM polarizations are the dominant mode in the wide and narrow waveguides, respectively, a perfect phase-matching condition in TM mode but a huge phase mismatching in TE mode can be achieved. Therefore, the TE mode is almost uncoupled regardless of device length but the TM mode can only completely couple to the cross port at an appropriate coupling length. An ultrashort (~8.13 um long) PBS is designed based on a silicon-on-insulator nanowire with a loading refractive index of 2.0 and a gap width of 200 nm. Numerical simulations show that the proposed PBS has a broad bandwidth (~100 nm) with large extinction ratio (> 10 dB) and low insertion loss ( 0.61 dB). The fabrication-error tolerance of the PBS is also discussed.

名稱Polarization Beam Splitter based on an Asymmetric Directional Coupler with Different Core Aspect Ratio
年度2013
類別研討會
摘要A polarization beamsplitter (PBS) based on asymmetrical directional coupler (ADC) is proposed by utilizing the evanescent coupling between a wide waveguide and a dielectric loaded narrow waveguide. The TM mode is design to be well coupled in the ADC. Meanwhile, since the aspect ratios of these two waveguides are different, the large phase mismatched TE mode results in negligible coupling. The simulation results show that the present PBS has a high extinction ratio of more than 20 dB.

摘要A highly sensitive, miniaturized, integrated optic refractive index sensor is proposed based on polarization rotation in waveguides. The sensitivity of the sensor can be increased by increasing the length of the waveguide rotator. Post-fabrication trimming technique can be used to adjust the detection range and eliminate the fabrication error of the device.

名稱Synthesis High Sensivity ZnO Cholesterol Biosensor with One Dimensional Nanostructures
年度2016
類別研討會
摘要Chelosterol ZnO biosensors were synthesized by hydrothermal method with pre-deposited ALD-ZnO seed layers. The ZnO nanostructures were examined by SEM, XRD, AFM, respectively. The XRD is used to analyze the crystal structures of ZnO seed layers that were grown by ALD process, then using SEM and AFM to analysis the surface morphologies of them. Growing of one dimensional ZnO nanostructures on seed layer of 10nm thickness, reveals high sensitivity of 3.15 uA (mg/dl)-1cm-2(121.96 uAmM-1cm-2) and low Km value of0.29mM in 25-100mg/dl cholesterol concentration range. The response time could be as low as 10seconds. In the study, it is found that increasing the aspect ratio of ZnO one dimensional nanostructure also increases the sensitivity and expends the linear measureable range of detecting cholesterol in solution. The thickness of seed layer has a significant influence on sensitivity for one dimensional nano ZnO cholesterol biosensor.
