Optical Surface Diffraction and Improved Lateral Resolution
Optical coherence plays an important role in the local field in the vicinity of surfaces where the incident and scatter field overlap (1). While phase differences are small in the optical nearfield, the longitudinal component [...]
Add-Drop Filters utilizing Vertically Coupled Microcavities in Silicon
Micro-resonant optical cavities facilitate dense integration of optical devices on a chip. Through vertical integration of devices, precise control over the critical dimension of the structure can be achieved. Add-drop multiplexers based on vertically coupled [...]
Simulation Studies of Plasmon Enhanced Evanescent Near-Field Optical Lithography
Evanescent Near-Field Optical Lithography (ENFOL) is an inexpensive route to nanolithography, overcoming the diffraction limitations of conventional optical technology. This paper details modelling work developed by the authors, to produce a predictive model that can [...]
Fabrication and Characterization of 3D Square Spiral Photonic Crystals
Three-dimensional photonic crystals can be fabricated using the glancing angle thin film deposition technique (GLAD). These nanostructured thin films consist of a periodic array of micrometer-sized silicon square spirals, as proposed by O. Toader and [...]
Preparation of Sb Doped SnO2 SPM Tips and their Use as Transparent Probes in STM Induced Light Hybrid Microscopy
Tätte T., Jacobsen V., Paalo M., Branscheid R., Kreiter M., Mäeorg U., Saal K., Lõhmus A., Kink I., Tartu University, EE
Development of various kinds of sharp needles has been in focus of investigators since their application as sensors in scanning probe microscopy. Although transparent and conductive tips lead to several fascinating applications like STM/SNOM hybrid [...]
Visible Light Emission from Si-related Nanostructures and the Effect of Ambient Atmosphere on Photoluminescence
Two different types of visible light emission were observed from the Si-related nanostructures prepared by vapor condensation in an Ar-5%O2 atmosphere at various working pressures (1, 30, 50, and 100 torr). The specimen prepared at [...]
UV Silicon Sensor Using Si Nanocrystals
Berman-Mendoza D., Aceves-Mijares M., Berriel-Valdos L., Domínguez-Horna C., Pedraza J., Falcony C., Carranza J., INAOE, MX
After the discovery of photoluminescence of silicon (Si) nanocrystals embedded in silicon dioxide a big effort has been done to understand such emission. However, almost not application of these characteristics can be found until now. [...]
Enhancement of Silicon Photon Emission with Nanostructure Array
Initiated by the high photon-emission nature of the porous silicon materials and the light transmission enhancement characteristics of the photonic crystals, the research of silicon Raman scattering of array nanostructures built by the electron beam [...]
Surface Enhanced Raman Scattering by 2D Photonic Crystals: Enhancement and Reproducibility
Netti M.C., Mahnkopf S., Lincoln J.R., Charlton M.D.B., Cox S.J., Ayliffe P., Zoorob M.E., Wilkinson J.S., Baumberg J.J., Perney N.M.B., Jaiswal S.L., Mesophotonics Ltd., UK
Surface Enhanced Raman Scattering (SERS) is a widely utilised technique to enhance the weak Raman spectrum of molecules, enabling detection and identification of ultralow concentrations of particular species. We show both experimentally and theoretically how [...]
Demonstration of Pulsed Silicon Raman Laser
Recently, Raman effect in silicon has been pursued for light generation and amplification by utilizing high Raman gain coefficient of silicon. However, free carrier generation due to two photon absorption limited the achieving high Raman [...]
A Two-Dimensional Numerical Simulation of Organic Light-Emitting Devices
Li Y., Lee B-S, Lee J.W., Chen P., Chen W-H, Lee B-S, Lee J.W., Lu C-S, Chen P., Chen W-H, National Chiao Tung University, TW
Organic light-emitting devices (OLEDs) add a completely new dimension to current display technology [1-3]. OLED displays are thinner, lighter, brighter, and cheaper to manufacture; which also consume less power than the current thin displays do. [...]
