All-optical wavelength conversion will be one of the most key technologies in all-optical network. Wavelngth converter using nonlinear effect can resolve wavelength contentions with its high transparency and subcarrier-multiplexed channels in a complex all-optical network model which is more beneficial than O/E/O method.
Periodically poled LiNbO3 crystal fiber for wavelength conversion is successfully grown by LHPG method with high-electric-field bias. It does not require conducting the metallic electrode to define domain period. The pitch depends on the frequency of applied external electric field and the growth speed. Domain period of 18.9 £gm for C-band wavelength converter and domain period of 15.45 £gm for tunable blue/green laser are demonstrated in this thesis. Micro-swing during growth is managed to assist poling process. More than 40 nm wavelength range of blue/green laser was generated and 10% internal SHG conversion efficiency was achieved. A simulation shows that maximum tuning range using a graded-period qusai-phase-matching structure can be as large as 33 nm.
With the improvement of uniformity, broadband design for cascaded processes, and waveguide structure, superior performance of periodically poled LiNbO3 crystal fiber can be achieved.
