All-optical transistor using an optical event horizon
Jens Bethge, Carsten Brée, Shalva Amiranashvili +3 more
We show by experiment that scattering of an optical pulse at an optical event horizon provides an unprecedented potential for controlling the properties of a light pulse with another light pulse. Most importantly, with proper parameter selection, a strong pulse can be switched by a 7 times less energetic pulse, which clearly sets our method apart from almost any other previously proposed optical transistor. Moreover, while a gate pulse may experience serious reshaping effects in the normal dispersion regime, a suitably chosen soliton does not dispersively spread or break up into multiple pulses, such that the solitonic switching scheme is cascadable.
