We report a 1550-nm 40-Gbit/s electro-absorption DFB laser diode module. Through the optimum design of the LD chip and the module, we successfully applied it to a 40-Gbit/s transponder for very short reach applications.
27Al NMR spectra of an equimolar (10 mM) Al(III)-citrate system were obtained at different temperatures. The linewidths of the signals decreased in the spectra recorded at elevated temperatures, which enabled us to unequivocally identify the resonance lines. From the spectrum recorded at 65 approximately C, a mononuclear Al(III)-citrate complex was… (More)
