Abstract: We have seen that some waveguides exhibit variable and increasing back reflection of single wavelength illumination over time, limiting their effectiveness and reliability. We have developed approaches to improve the transmission of these waveguides. We have found that by modulating the illumination wavelength over a small wavelength range we can reduce or eliminate this back reflection from the waveguide. In addition, we describe the writing and erasing of gratings within SiON waveguides by forming standing waves. Methods, systems, instruments, and devices are described that provide improved transmission of light through such waveguides.
