We demonstrate an easily fabricated all-optical and freely reconfigurable method of controlling the propagating characteristics of the optic path within a planar waveguide with low insertion losses by employing the optical patterning of the refractive index of an erasable and rewriteable photosensitive liquid crystal polymer cladding layer.

    Optical waveguides with a high refractive index contrast were fabricated on silicon-on-insulator (SOI) and polysilicon. The attenuation of 2dB/cm was achieved for SOI, and 11 dB/cm for hydrogenated polysilicon waveguides. Unlike in SOI waveguides, where the main contribution to attenuation is...
