(Color online) Computed band diagram for transverse magnetic (TM) and transverse electric (TE) modes of a triangular lattice of silicon rods having an air filling factor equal to 0.5. An effective index method is used to take into account the thickness of the rods.
(Color online) Photoluminescence spectra recorded above SOI and rod array in the same conditions. The SOI intensity is ten times magnified and a SEM view of the triangular Si rods array is presented.
(Color online) Experimental emission diagrams of the Si rod array for different wavelengths (1040, 1046, and ). On the figure, the green area indicates the experimental collection setup geometric characteristics.
(Color online) Poynting vector amplitude finite difference time domain calculations of the radiation of dipole sources, respectively, located inside a SOI photonic crystal supporting a low group velocity mode at point and inside the silicon film of SOI. The amounts of light radiated in air and in the substrate are indicated on the figure.
