A fiber Bragg grating (FBG) sensor system based on a semiconductor optical amplifier connected in a ring cavity configuration is proposed. The proposed configuration produces high power signal with good extinction ratio for FBGs with /spl sim/1% reflectivity. A sensor system consists of four group of three FBGs of different wavelengths was constructed to(More)
We report the fabrication, and electrical and optical characterization, of solution-liquid-solid (SLS) grown CdSe nanowire field-effect transistors. Ultrathin nanowires (7–12 nm diameters) with lengths between 1 $m and 10 $m were grown by the SLS technique. Al-CdSe-Al junctions are then defined over oxidized Si substrate using photolithography. The(More)

Biofilm formation is one of the major problems of recirculating cooling water systems which detriments the life of equipment, through biocorrosion or microbiologically influenced corrosion (MIC). Sulfate reducing bacteria (SRB) are considered to be the major bacterial group involved in MIC. In the present study, SRB cultures are isolated from aeration basin(More)
