Abstract
We demonstrate a new mechanism for optical bistability(OB) in integrated optics(IO): light-induced-desorption of molecules from the surface of the waveguide, or out of pores in the waveguiding film itself, and their re-adsorption from the gaseous phase, respectively. By this process the effective refractive index N of the waveguide depends on the guided power P’. This effect is the basis of intrinsic dispersive OB of the following IO devices: input grating couplers on planar waveguides, Fabry-Perot or ring resonators, and presumably Bragg reflectors and directional couplers.KeywordsBragg ReflectorRing ResonatorEffective Refractive IndexDiffract BeamPlanar WaveguideThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
