Abstract

A first experimental demonstration of a planar superprism in silicon microphotonics technology using silicon on insulator (SOI) substrates is presented. Experimental results for anomalous wavelength-dependent angular dispersion in SOI triangular lattice planar photonic crystals are reported. An angular swing of 14° is measured for light propagating near the Γ-K direction as the input wavelength is changed from 1295 nm to 1330 nm, which corresponds to an angular dispersion of 0.4°/nm. For the Γ-M direction, a negative wavelength dispersion has been recorded. An opposite sign angular deviation of 21° is observed as the input wavelength is changed from 1316 nm to 1332 nm, i.e. a dispersion of 1.3°/nm.
