国家自然科学基金委员会信息科学部召开光学超晶格研讨会光学超晶格材料引入晶格场参与非线性光学过程，产生了许多全新的概念和非常丰富的内涵，开辟了一个全新的研究领域，已成为物理学、光学和材料科学共同关注的问题，可望如同当今半导体超晶格中电子“能带工程”所取... National Natural Science Foundation of China held a super-lattice optical information seminar optical superlattice materials into the lattice field to participate in nonlinear optical processes, resulting in many new concepts and very rich connotations, opened up a whole new field of research, Has become a common concern in physics, optics and materials science, and is expected to be the same as today’s electronic “band engineering” semiconductor superlattices.
