Abstract:
A beam-steering device, such as a steerable electro-evanescent optical refractor, has a planar waveguide region between an incoupler and an outcoupler. Each region has a substrate and a plurality of thin-film layers, such as a subcladding layer over the substrate and a core layer over the subcladding. For at least one coupler, at least two of the thin-film layers have spatially varying optical thicknesses due to, for example, the subcladding and the core being tapered with decreasing thicknesses from the waveguide region to the corresponding facet of the BS device. Alternatively, spatially varying optical thickness can be achieved by spatially varying a layer's refractive index. The coupler has a FWHM bandwidth and a FWHM coupling angle tolerance that greatly exceed those achievable using conventional Ulrich couplers.

Claim (Index 14):
The article of  claim 13 , wherein:\n the tapered core layer of the incoupler has an incoupler core taper angle; and the tapered core layer of the outcoupler has an outcoupler core taper angle that is the same as the incoupler core taper angle.
