Tunable Fano-Resonance in Terahertz Metamaterials
Terahertz radiation (THz) is defined to have frequencies from 0.1-10 THz (1 THz=1e12 Hz). This radiation lies between microwave and infrared radiations in the electromagnetic spectrum. Metamaterials are designed periodic materials that show exotic properties to light and sound. ... 詳細を見る
Design and Characterization of MOEMS Optical Tweezers
Optical tweezers work on the idea of non-contact Optical Pressure felt by transparent particles, when shined by coherent light source such as lasers. On the other hand when light falls on the metal it excites the electron inside it and make them free. When these free electron cloud ... 詳細を見る
Commercial Special Fibers for Sensing Applications
In a solid core PCF, structural parameters and the number of rings in the cladding region decide confinement losses, dispersion coefficients as well as bending losses. This paper evaluates some of commercially available solid core photonic crystal fibers. The dispersion coefficients and ... 詳細を見る
Demonstration of All-Optical NAND Logic Gate Using Photonic Integrated Circuits
A logic gate performs a certain Boolean logic operation on one or more logical inputs and produces a single logical output. The logic values are either “true” or “false.” Logic gates are bistable devices, that is, they may yield one of these two possible stable outputs. The NAND logic is ... 詳細を見る
Improving Detection Sensitivity for Nanoscale Targets Through Combined Photonic and Plasmonic Techniques
Photonic technique such as the whispering gallery mode (WGM) is often used for detection of small particles like bacteria and viruses. It offers good detection sensitivity and is advantageous over other detection techniques because the detection can be label free. However, the detection ... 詳細を見る

Optical Forces and Torques Acting on Non-spherical Metallic Nanoparticles
Metallic nanoparticles (NPs) are nowadays used in various areas of biology, chemistry or physics. Focused laser beams, optical tweezers, may be used to manipulate such NPs. However, experimental studies showed that there is a discrepancy between their predicted and observed behavior. ... 詳細を見る
Modeling and Simulation of Silicon Optical MEMS Switches Controlled by Electrostatic Field
The use of optical sensors in the industry is still growing. A transmission of signal from the sensors is mostly done by optical fibers. Switching the signals from optical paths may be done by using micromechanical silicon switches. The main advantage is an ability to transmit data from ... 詳細を見る
Simulation of Light Coupling Reciprocity for a Photonic Grating
SOI (Silicon on Insulator) technology utilizes silicon components on SiO2 layer. Propagating electric field distribution in a SOI waveguide is called mode of the waveguide. Photonic gratings are formed by etching grooves on the top of a waveguide. Gratings can operate in two directions. ... 詳細を見る
