Abstract
In this paper, we have proposed a principle to design wideband, low
dispersion and temperature stabilized slow light structure in slotted photonic
crystal waveguide (SPCW). The infiltration of the silicon photonic crystal with
polymer will enhance the slow light and increase the group index, whereas the
different signs of thermo-optic coefficients of polymer and silicon make the
proposed structure stable on temperature variation over
60°C and improves the group index-bandwidth products
of the designed structure. The SPCW structure is modified to maximize the slow light
effect and minimize the dependence of the group index and hence the group velocity
dispersion to temperature.
