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 fundamental frequency field (at v) is incident ...

Optical Bistability and its Computation

Optical bistability in axially modulated OmniGuide fibers.

We demonstrate the feasibility of optical bistability in an axially modulated nonlinear OmniGuide fiber through analytical theory and detailed numerical experiments. At 1.55-microm carrier wavelength, the in-fiber devices that we propose can operate with only a few tens of milliwatts of power, can have a nearly instantaneous response and recovery time, and can be shorter than 100 microm.
