The present invention provides methods of tuning the optical properties, such as the channel center wavelengths, of an integrated optical waveguide device by providing a device, such as a wavelength division multiplexer or demultiplexer, which contains an organic material, and fine tuning the device by exposing the organic material to at least one incremental step of UV irradiation.

Tuning of optical waveguide devices containing an organic material

A method for forming a substantially flat planar lightwave optical circuit which has a substantially flat planar silica substrate and a sintered glassy lightguiding layer over the silica substrate. The structure is given a post treatment at an elevated temperature for a time sufficient to flatten said structure and overcome any distortion caused by the difference in the coefficient of thermal expansion of the substrate and any glassy layers formed over the substrate. Alternatively, the silica substrate may be heated and presagged to a predetermined degree to compensate for distortion or warpage which will occur in later processing.
