Abstract
A wavelength converter includes a supporting substrate and a ferroelectric substrate, the ferroelectric substrate includes at least one waveguide facing the supporting substrate and at least one wavelength-filtering pattern positioned between the waveguide and the supporting substrate, the waveguide includes a plurality of inverted domains and non-inverted domains configured to convert an infrared light into a green light, and the infrared light emitted from the semiconductor laser enters the waveguide of the wavelength converter. For example, the wavelength-filtering pattern includes a Bragg grating.
