Abstract
A nonlinear optical material includes nitride layers and non-nitride layers which are alternately deposited, wherein the non-nitride layers include at least one non-nitride selected from the group consisting of oxides, carbides and semiconductors and at least one type of semiconductor fine particles having a band gap smaller than a band gap of the nitride and the non-nitride, which particles are dispersed in the non-nitride layer.
