The Study and Fabrication of Quasi-phase-matched LiNbO3 Crystal Fiber for Wavelength Conversion

All-optical wavelength conversion is necessary for efficient managing and routing optical signals in a complex all-optical network model. With the bit-rate increases as time evolves, all-optical conversion will become more promising due to its high transparency for data rate and format and the low cost penalty compared with O/E/O method.
Periodically poled LiNbO3 crystal fiber (PPLNCF) for wavelength conversion is successfully grown by LHPG method with in situ electric field bias. The pitch depends on the frequency of applied external electric field. Domain period of 9.76 microms and crystal length over 160 mm are demonstrated in this thesis. Electrically induced micro-swing during growth is managed to assist poling process. After the optical test, 0.27% peak offset shows the accuracy of our fabrication. The wavelength and temperature bandwidths were measured to be 17.2 nm and 42.8oC.
With the improvement of uniformity, broadband design, and the implementation of guiding structure, high quality PPLNCF will be widely promoted for its superior performance.
