    The nonlinear properties of a distributed feedback grating in a waveguide characterized by a diffusive thermal nonlinearity were investigated experimentally. Reflection and transmission were measured in an InSb planar structure, and all-optical tuning of the reflectivity was achieved either by a...

    A measurement of the insertion loss and crosstalk in folded, 100 GHz, arrayed waveguide multiplexers as a function of the number of grating waveguides is described. The number of grating waveguides can be varied in a single device to evaluate power truncation effects with high accuracy. We show...

    We report on a new method to excite surface plasmon polaritons on a thin metal slab surface using an elastomeric grating which is fabricated by replica molding technique. The grating is placed on the metal surface which creates a periodic perturbation on the surface matching the momentum of the...

    The four-wave mixing (FWM) equations in single-mode fibers are investigated. It is found that there are four types of FWM, two of them are well known and the others have been known little. FWM can lead to modulation instability (MI) of continuous optical waves. The perturbations will rapidly be...
