Rare-earth-ion doped KY(WO4)2 optical waveguides grown by liquid-phase epitaxy
Rare-earth-ion doped KY(WO4)2 (hereafter KYW) is a promising material for novel solid-state lasers. Low laser thresholds, high efficiencies, high output powers, and third-order nonlinear effects have stimulated research towards miniaturized thin-film waveguide lasers and amplifiers for future photonic devices. Active films can be fabricated by liquid-phase epitaxy (LPE), pulsed laser deposition...
متن کاملProgress on micro-structured KY(WO4)2 waveguides for optically active devices
The optical properties of rare-earth-ion (RE) doped KY(WO4)2 (KYW) form an excellent basis for the realization of optically active devices such as lasers and amplifiers. External-cavity laser experiments on KYW:Yb planar waveguides confirmed these predictions by high slope efficiencies up to 80%. In-house equipment enables the epitaxial growth of KYW:RE layers and their optical characterization...

Rare-earth-ion-doped monoclinic potassium double tungstates KY(WO4)2, KGd(WO4)2, and KLu(WO4)2 are excellent host materials for solid-state lasers [1]. High-quality KY(WO4)2 optical waveguides were grown and laser operation was demonstrated for the first time [2]. Co-doping a KY(WO4)2 layer with Gd 3+ and Lu 3+ ions allows for lattice-matched layers with increased refractive index contrast with...
متن کاملYb-doped KY(WO4)2 planar waveguide laser.
High-quality monoclinic KY(WO4)2 optical waveguides were grown by liquid-phase epitaxy, and laser operation of an Yb-doped KY(WO4)2 waveguide was demonstrated for the first time to our knowledge. Continuous-wave laser emission near 1 microm was achieved with both surface and buried planar waveguides. An output power of 290 mW was obtained in the fundamental mode and the slope efficiency was abo...
متن کاملOn-chip Integrated Amplifiers and Lasers Utilizing Rare-earth-ion Activation
This contribution reviews our recent results on rare-earth-ion-doped integrated amplifiers and lasers. We have concentrated our efforts on complex-doped polymers [1], amorphous Al2O3 [2], and crystalline potassium double tungstates [3]. A polymer host material, based on a cycloaliphatic diepoxy cured with a fluorinated dianhydride, has been developed [4]. When activated with the rare-earth-ion-...
