Photonic crystals have various unique optical properties [1], [2] and are thus considered promising candidates as key platforms for future ultra-small large-scale photonic integrated circuits (PTCs). It has been theoretically predicted that various optical properties of photonic crystals are advantageous as regards this goal. The selection of component materials is very im¬portant if we are to realize PICs by using photonic crys¬tals. With conventional optoelectronic circuits (such as f 11 V semiconductor PICs or silica planar lightwave cir¬cuits [3]), a relatively small refractive index difference is normally used to reduce the scattering loss, and fine index variation is essential to PIC design. This means that Si is not a good choice for optoelectronic use because fine index modulation is difficult.
