Program |
Lithium niobate is a wide-band-gap crystalline dielectric material with large second-order nonlinear-optical coefficients. The ability to structure lithium niobate on the micro- and nanometer scale has led to a boost of the interest in this material. The talk will review novel developments where lithium niobate gratings, waveguides, and resonators are employed. This involves, e.g., holographic gratings, ridge waveguides, and whispering-gallery-mode cavities. Linear and nonlinear diffraction, slowing down of light, sum-frequency mixing for making quantum detectors in the infrared, generation of terahertz waves and very-high-efficiency second-harmonic generation became possible because of the remarkable properties of lithium niobate crystals. |
