Abstract

In this paper, we propose a device based on planar waveguides with multiple slanted quasi-phase-matching gratings to achieve a significant increase in the bandwidth of second-harmonic generation. We show that an appropriate device design can significantly flatten the efficiency of second-harmonic generation as a function of input pump frequency. The design using slanted gratings allows for the fundamental and second harmonic to be noncollinear and thus makes the collection of the generated wave easy. Numerical simulations are performed in a potassium titanyl phosphate (KTP) planar waveguide, and we show the analysis and results for increased bandwidth using two, three, and four gratings, which can be easily extended to more gratings without any loss of generality.
