Harmonic wave generating element for coherent light having short wavelength |
| abstract |
A harmonic wave generating element of a discrete structure for reducing loss of light caused by scattering and improving efficiency of conversion has a polarization-inverted portion and a non-inverted portion periodically formed in a non-linear optical material to perform quasi phase matching between incident light and an n-th harmonic wave and to form a discrete optical waveguide structure, in which the boundary between the polarization-inverted portion and the non-inverted portion has a generally curved surface. And a waveguide structure is formed in the non-linear optical material and provides a mechanism for generating n-th harmonic wave and a lens-like focusing mechanism for facilitating the optical coupling of light at an end surface of incidence. |
