Ridge optical waveguide curved in a KTiOPO4 single crystal for triple photon generation: preliminary characterization by birefringence phase-matched third-harmonic generation

Résumé

Ridge waveguides carved in bulk nonlinear crystals such as KTiOPO4 (KTP) are used to reach a strong confinement of electromagnetic waves with large second-order or third-order non-linearity. We report on our recent experiments where we show the possibility to shape the birefringence phase-matching (BPM) conditions for direct Third-Harmonic Generation (THG: ω + ω + ω → 3ω) in micrometric KTP ridge waveguides by acting on their transverse dimensions. The real goal of this preliminary study is to design quantum optical experiments based on Triple Photons Generation (TPG: 3ω → ω + ω + ω) that is the reverse process of THG, thus exhibiting the same BPM conditions.
