Nonlinear optical element and uses thereof.

摘要

The nonlinear optical element (30) includes a substrate (32) and one or more transparent microspheres (34) made of a nonlinear optical active substance system fixed to the substrate, or the nonlinear optical element includes one or more transparent microspheres contacting a solid medium (36) and fixed to the substrate. The element can be used for controlling nonlinear optical characteristics such as light amplification, optical switching, injection mode locking, and coupling of whispering gallery modes. <IMAGE>
