Time-resolved ultrafast all-optical switching in directional couplers with second-order nonlinearity

Solntsev, Alexander; Neshev, Dragomir; Schiek, Roland


Nonlinear directional couplers (NLDC) allow for ultrafast all-optical switching. To date, various types of NLDCs have been studied, predominantly based on the Kerr [1] or cascaded quadratic nonlinearity [2] in second-harmonic generation (SHG). In the later case the switching can occur at lower powers because of a propagating-wave resonance effect. While a number of experiments to characterise the pulse propagation in Kerr-type couplers exist, till now the temporal behavior of short pulses in...[Show more]
