Phase-matched guided-wave optical bistability in x s2d optical resonators


Cascaded second-order nonlinear effects attract great interest because of their potential use in devices that require nonlinear (NL) phase shifts. – 9 It is only recently that the case of x s2d distributed couplers in the cascading regime has been considered. The nonlinear effect studied in Ref. 10 is second-harmonic generation, for which only the… (More)
