“The net result is the creation of a nonlinear splitter in which the light pulses are routed to two different outputs based on their energies, which enables switching to occur in less than 50 femtoseconds (a femtosecond is a quadrillionth of a second). By comparison, state-of-the-art electronic switches take tens of picoseconds (a picosecond is a trillionth of a second), a difference of many orders of magnitude.”
