Second-harmonic generation from porous silicon with a magnitude of two orders greater than that from silicon crystalline wafers has been observed. The measured effective second-order nonlinear susceptibility [formula Omitted] for a p-type porous silicon is 1.96 × 10-7 esu which is estimated on the base of a bulk property rather than on quantum confinement owing to its large surface to volume ratio.
