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.

Wavelength converter and green light source and projection apparatus using the same

A wavelength converter structure comprises a supporting substrate, a ferroelectric substrate having at least one ridge waveguide including a plurality of periodic poled regions positioned on a first side of the ferroelectric substrate, and at least one controlling pattern positioned on a second side of the ferroelectric substrate. The ridge waveguide is joined to the supporting substrate via an adhesive, and the second side is opposite to the first side.
