Fabrication and Characterization of Wavelength Conversion Device with Periodically Poled Ridge-type Waveguide in MgO:LiNbO3

Wavelength converting devices with a ridge-type waveguide in periodically poled MgO:LiNbO3 are made and characterized. The experimental results are compared with theoretical analysis on the effects of waveguide dimension and duty ratio of the periodically poled structure. To show the relationship of the conversion efficiency to those factors, a new measurement system is configured. That experimental results show that the center wavelength, normalized conversion efficiency and full width half maximum of the conversion efficiency curve are 1067.45 nm, 90.7%/Wcm(2) and 0.17 nm, respectively. Also, the estimated results of the duty period and full width half maximum of the conversion efficiency from theoretical calculations agreed well with experimental results with the errors of 0.016 mu m and 0.01 nm.
