Abstract
We show that photonic crystals
with ring-shaped holes (RPhCs) exhibit superior properties compared to
conventional photonic crystals (PhCs). At low air-fill factors RPhCs can
have a larger bandgap than conventional PhCs. Moreover, RPhC waveguides
with both high group index and small group velocity dispersion can be
designed. RPhC waveguides are also more sensitive to external refractive index changes, which is attractive for sensor applications. Finally we set up a procedure to pattern RPhCs in silicon-on-insulator.
