Unexpectedly, the crystals exhibited the largest nonlinear optical response of any known crystal. (phys.org)
The thin semiconductor layers confine electrons into desired quantum states, and gold nanocrosses resonate at input and output frequencies to enable the the nonlinear optical response of the mirror. (sciencedaily.com)
The research team led by UT Austin's Department of Electrical and Computer Engineering professors Mikhail Belkin and Andrea Alu, in collaboration with colleagues from the Technical University of Munich, has created thin - film nonlinear metamaterials with optical response many orders of magnitude larger than that of traditional nonlinear materials.
