WAVELENGTH CONVERSION ELEMENT |
摘要 |
<p>It is provided a wavelength converting device comprising a periodic domain inversion structure for converting a wavelength of a fundamental wave to generate a harmonic wave. The wavelength conversion device includes a ferroelectric substrate and the periodic domain inversion structure formed in the ferroelectric substrate. A vertical domain inversion boundary of the periodic domain inversion structure is inclined with respect to a normal line of an upper face of the ferroelectric substrate, provided that the ferroelectric substrate is viewed in a cross section parallel with a propagating direction of the fundamental wave and parallel with the normal line of the upper face.</p> |
