Second harmonic generation element and a process for producing the same |
| 摘要 |
A second harmonic generation element including a single crystal substrate having a fundamental composition of K3Li2-2x(Nb1-yTay)5+5zO15-x+12.5z and an optical waveguide made of an epitaxial film with a fundamental composition of K3Li2-2a(Nb1-bTab)5+5cO15-a+12.5c and refractive index different from that of the single crystal substrate, wherein:-0.5</=a, x</=0.6250</=b, y</=0.50.8</=(5-2x)/(5+5z), (5-2a)/(5+5c)</=1.2.
