Description: |
SEM images of suspended silicon phoxonic crystal membranes. (a) Corrugated waveguide with holes that support a bandgap for TE-polarized photons around 1.55 micrometres and 4 GHz phonons (top panel). The introduction of a λ/4 defect (bottom panel) should lead to the localization of photons and phonons in a nanoscale volume. (b) Removal of the buried oxide leads to a suspended phoxonic crystal that facilitates the excitation and propagation of GHz phonons. (c) Top-view of a line defect created in a honeycomb-lattice. The structure can confine and guide slow photons and phonons simultaneously |
