Abstract: The saturated absorption spectra and line widths of the Cs-D 2 line were observed as a function of the incident power. A minimum spectral width of 20 MHz was obtained when the incident power ...

Analysis of Spectral and Energy Efficiency Tradeoff in Single-Line Rate WDM Links Abstract: This paper investigates, through simulations, the tradeoff between energy efficiency (EE) and the overall ...
