Abstract:
A wavelength tunable optoelectronic device, comprising:an optoelectronic structure made of a ferroelectric material; a first and a second channel waveguide provided in the optoelectronic structure, the first and second waveguides being adjacent at least along a coupling region, a periodically poled structure being provided in said coupling region, at least one of the first and second channel waveguides being untouched by said periodically poled structure; and means for generating an electric field of a selectable amplitude in the coupling region through both the first and second waveguides, the electric field enabling a coupling of light of a coupling wavelength between the first and second waveguides in said coupling region, the amplitude of said electric field in the untouched waveguide determining the coupling wavelength.
