Abstract

Using a novel self-cascaded first-order second-harmonic generation (SHG) and third-order sum-frequency generation (SFG) in a ZnO periodically poled lithium niobate crystal fiber, tunable blue–green light was demonstrated. At a domain pitch of 15.45 μ m , the SHG signal and its fundamental signal at 1423.9 nm can satisfy the third-order SFG quasi-phase-matched (QPM) condition. The measured SHG power at 714.2 nm was 12.25 mW under 100 mW input power, and the estimated nonlinear coefficient ( d 33 ) achieved was 25.3 pm V . The self-cascaded SHG + SFG power measured at 477.1 nm was 700 μ W under 350 mW input power. The maximum internal efficiency of the SHG is 14.84%. The tuning range of the self-cascaded SHG and SFG generated tunable blue–green light was more than 40 nm , from 471.3 to 515 nm . The maximum simulated 3 dB bandwidth achieved using a gradient-period QPM structure is 196 nm , which is from 1476 to 1672 nm . The gain-bandwidth product of the self-cascaded SHG and SFG processes decreases drastically as the bandwidth is broadened.
