  • Patent number: 10585242
    Abstract: The channel waveguides disclosed herein have bend compensation in the form of at least one compensated bend section. The channel waveguides are formed in a glass-based substrate having a glass-based matrix. The channel waveguide has an waveguide IOX region with a straight section and a bend section. The waveguide IOX region at the bend section is superimposed with a quasi-linear modifying IOX region to form a compensated bend IOX region that defines the compensated bend section. The compensated bend section has a reduced amount of optical loss as compared to if the compensated bend section had a refractive index profile that was the same as the straight section. Methods of forming the compensated bend sections for the channel waveguides are also disclosed.
