Integrated terahertz optoelectronics
Currently, terahertz (THz) optical systems are based on bulky free-space optics. This is due to the lack of a common platform onto which different THz components, e.g., source, waveguide, modulator and detector, can be ...
Silicon-based MZI modulator for MIR wavelengths
We report here a simulation results on the design of an electrooptic modulator at a wavelength of 2μm, using a free-carrier depletion-based silicon Mach-Zehender modulator.
Extraction of plant-based capsules for microencapsulation applications
Microcapsules derived from plant-based spores or pollen provide a robust platform for a diverse range of microencapsulation applications. Sporopollenin exine capsules (SECs) are obtained when spores or pollen are processed ...
Spoofing speech detection using temporal convolutional neural network
Spoofing speech detection aims to differentiate spoofing speech from natural speech. Frame-based features are usually used in most of previous works. Although multiple frames or dynamic features are used to form a super-vector ...
Interactive Teachable Cognitive Agents: Smart Building Blocks for Multiagent Systems
Developing a complex intelligent system by abstracting their behaviors, functionalities, and reasoning mechanisms can be tedious and time consuming. In this paper, we present a framework for developing an application or ...
Nanotechnology formulations for antibacterial free fatty acids and monoglycerides
Free fatty acids and monoglycerides have long been known to possess broad-spectrum antibacterial activity that is based on lytic behavior against bacterial cell membranes. Considering the growing challenges of drug-resistant ...
On the influence of workpiece material on friction in microforming and lubricant effectiveness
The frictional behaviors between metal forming tool and three different metallic materials were evaluated using the modified T-Shape test. A mathematical function is proposed to describe the calibration curves for different ...
Spreading of a ferrofluid core in three-stream micromixer channels
Spreading of a water based ferrofluid core, cladded by a diamagnetic fluid, in three-stream micromixer channels was studied. This spreading, induced by an external magnetic field, is known as magnetofluidic spreading (MFS). ...
Broadband tunable hybrid photonic crystal-nanowire light emitter
We integrate about 100 single cadmium selenide semiconductor nanowires in silicon nitride photonic crystal cavities in a single processing run. Room temperature measurements reveal a single and narrow emission linewidth, ...
A compact opto-fluidic platform for chemical sensing with photonic crystal fibers
We report a compact opto-fluidic platform capable of continuous analyte loading and unloading with a 3 dB optical insertion loss. The customized opto-fluidic manipulator enabled infiltration of photonic crystal fibers ...
