Broadband Nonlinear Frequency Conversion

Haim Suchowski, Barry D. Bruner, Ady Arie and Yaron Silberberg

Researchers are working to develop new techniques for nonlinear frequency conversion as well as new crystal design structures to help meet this need. Their work is leading to applications in optical communications, metrology and other areas.

Most of the optical phenomena that we encounter in everyday life—such as refraction, absorption and dispersion—occur in the realm of linear optics. With these types of linear optical effects, the intensity or propagation direction of the light wave can change based on the interaction between light and matter. However, other properties of light—in particular, the spectrum of colors contained in the beam—remain completely unaffected.
