Nonlinear directional coupler based on Rb:KTP-waveguides

Review of the Structure and Processing-Defect-Property Relationships of Potassium Titanyl Phosphate: A Strategy for Novel Thin-Film Photonic Devices

“…To create ultrahigh-speed long-distance optical fiber communications systems and implement optical information processing systems, various devices having less than 10 ps high-speed characteristics are required. 130 Buritskii and co-workers have proposed the use of KTP based waveguides for all-optical switching. The passing of subnanosecond light pulses through Rb-KTP nonlinear directional coupler has been achieved with nonlinear switching of 40% of the input light power (5 kW).…”

Theoretical research of the spin-Hamiltonian parameters for two rhombic W5+ centers in KTiOPO4 (KTP) crystal through a two-mechanism model

“…These unique features enable wide applications in many optic, photoelectronic and integrated optical fields, for instance, optical parametric oscillation (OPO), optical parametric generator (OPG), optical parametric amplifier (OPA), second harmonic generation (SHG), phase modulators, nonlinear directional couplers and optical waveguides [1][2][3][4][5][6][7][8][9]. The crystals properties can be modified by the impurities, e. g., transition-metal and rareearth ions, thus affecting the applications.…”

Visible and near-infrared optical properties of a proton-implanted KTP waveguide

“…With all these unique features, KTP crystals have been widely used in various types of important integrated optic fields, for example, switches [3], phase modulators [4], amplitude modulators [5], and nonlinear directional couplers [6]. In the last decade, the KTP crystal has attracted significant attention with regard to frequency doubling [7] and frequency conversion [8], especially under the situation of low power density.…”
