Intrinsic eigenstate spectrum of planar multilayer stacks of two-dimensional photonic crystals.
A specific class of planar photonic crystals is investigated that provides a condensed matter combining the properties of planar multilayer stacks and two-dimensional photonic crystals in order to achieve large partial bandgaps in the eigenstate spectrum. These gaps are larger than the directionally dependent and polarization-dependent partial gaps of photonic crystal slabs. Full in-plane gaps are demonstrated numerically. Strong dispersion, waveguide confinement, high Q-cavities, and alternative photonic signal processing are feasible with these structures.
