Birefringent Nanostructured Silicon: New Promising Material for Linear and Nonlinear Optics

Abstract

Porous Si layers produced by anisotropic electrochemical etching of bulk Si exhibit strong in-plane birefringence which depends on the sizes of Si nanocrystals spacing between them and dielectric properties of their surrounding media. Second harmonic generation experiments have revealed phase matching conditions for wave interaction in the layers. Furthermore they can serve as a phase-matching matrix for optically nonlinear substance incorporated in their pores. This finding can significantly expand the choice of nonlinear optical media since their anomalous dispersion is not strictly required for phase matching conditions.
