We present single- and multifrequency Brillouin lasers based on chalcogenide photonic chip. The high Brillouin gain of chalcogenide and the small waveguide cross-section make it possible to achieve lasing in a few centimeter long waveguide.
This paper describes novel glass micropipette thermal sensor fabricated in a cost-effective manner and thermal conductivity measurement of carbon nanotubes (CNT) thin film using the developed sensor. Various micrometer-sized sensors, which range from 2 µm to 30 µm, were produced and tested. The capability of the sensor in measuring thermal fluctuation at micro level with an accuracy of ±0.01°C is...
A novel technique for fabricating high-resolution micropipette thermal sensors using inexpensive materials was developed. The technique can be implemented relatively easily in a laboratory setting. The micropipette sensors were constructed by filling a metal inside a glass micropipette and coating a thin film on the outer surface of a glass micropipette by PVD (Physical Vapor Deposition), so that...
Graphene is a new advanced material for microelectronics. Graphene films can be prepared by different techniques. One of the promising methods is the production of stable dispersions of graphene in water or organic solvents. We have developed a new approach for preparation of easily soluble expanded graphite using fluorinated graphite intercalation compounds as starting materials. Graphene sheets...
