This paper presents an ultra-wideband DFB laser array with a 4×3 matrix configuration and 5 nm wavelength spacing. Using the reconstruction-equivalent-chirp technique, precise wavelength control is ...
In order to determine arbitrary impedance ratios, PTB implemented an impedance bridge based on pulse-driven Josephson arrays. The sine-waves generated by these arrays possess high spectral purity and ...
