Other methods have been proposed to use aperiodically poled PPLN [8, 9] or chirped PPLN . However, despite a theoretically estimated large bandwidth of 1045.9 nm centered at 3.5 μm, the effective … Web(a) Firstly, cut 3-inch support and PPLN wafers into bulk crystals with the same size. Second, the ridge waveguide and groove are fabricated on the PPLN and support crystals, respectively. Third, glue the PPLN with ridge waveguide and the support piece with groove into a single bulk structure.
