Article: P-i-n junction quantum dot saturable absorber mirror: electrical control of ultrafast dynamics.
[show abstract] [hide abstract]
ABSTRACT: We report on nonlinear optical properties of a p-i-n junction quantum dot saturable absorber based on InGaAs/GaAs. Absorption recovery dynamics and nonlinear reflectivity are investigated for different reverse bias and pump power conditions. A decrease in absorption recovery time of nearly two orders of magnitude is demonstrated by applying a voltage between 0 and -20 V. The saturable absorber modulation depth and saturation fluence are found to be independent from the applied reverse bias.Optics Express 04/2012; 20(8):9038-45. · 3.59 Impact Factor
