This paper proposes a new thin-film superconducting fault current limiter (SFCL) that is composed of double-sided thin films to improve the compactness of SFCL systems. In the double-sided design with assembling SFCL units on a wafer comes a possibility of freeing from the negative effect of magnetic flux penetration at the film edges by orienting current paths and taking advantage of thermal interplay...
100 mum-stripe, DFB diode lasers have been realized with 50% wall-plug efficiency at THS=25degC and 3 W CW power. Narrow spectral widths of 3Aring FWHM were achieved to CW power in excess of 5 W.
