SiON-based integrated optics devices for WDM networks

Two wavelength-filtering examples show that, due to the small bend radius, complex devices consisting of many optical building blocks can be made using SiON waveguide technology. Using ring resonators, phase-filtering devices such as dispersion compensators can also be made. Owing to the low-transmission-loss waveguides and low-loss coupling to standard single-mode fiber, the high device complexity does not come at the expense of high losses
