Abstract

A novel wavelength converter using LiNbO₃ waveguide ring resonator is proposed and simulated. In the design, a new wavelength is generated by combining the second harmonic generation (SHG) and the difference frequency generation (DFG). The quasi-phase-matched condition is achieved by periodically domain inverted lithium niobate crystal. A waveguide ring and four 1x2 beam splitters/combiners are used to link the SHG and SFG structures. The 1x2 beam splitter/combiners are carefully designed so that only the SHG signal at λ=0.77μm can stay inside the ring while the pumping signal at λ=1.54μm, idler signal at λ=1.55μm, and the converted signal at λ=1.53μm can coupled into and out of the ring. Therefore, the SHG signal, served as intermediate pumping source for the DFG, keeps circulating inside the ring and form resonance to gain higher power and to achieve higher conversion rate. The detail design is described and the design concept is proved by the simulation results.
