Multiple-mode phase matching in a single-crystal lithium niobate waveguide for three-wave mixing Download: 917次
Abstract
Developing natural “free space” frequency upconversion is essential for photonic integrated circuits. In a single-crystal lithium niobate thin film planar waveguide of less than 1 μm thickness, we achieve type I and type II mode phase-matching conditions simultaneously for this thin film planar waveguide. Finally, by employing the mode phase matching of e + e → e with d 33 at 1018 nm, we successfully achieve a green second-harmonic wave output with the conversion efficiency of 0.12 % / ( W · cm 2 ) , which verifies one of our simulation results. The rich mode phase matching for three-wave mixing in a thin film planar waveguide may provide a potential application in on-chip frequency upconversions for integrated photonic and quantum devices.
