4. 2. Quasi-phase matched devices in Rb-doped KTiOPO4: counterpropagating nonlinear interactions, domain dynamics, and waveguides

   Author : Patrick Mutter; Carlota Canalias; Christopher Phillips; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Abstract : Abstract Nonlinear interactions involving counterpropagating photons are gaining much attention in classical and quantum optics due to their unique properties that are very difficult, if not impossible, to realize in conventional co-propagating three-wave mixing. However, the large phase mismatch between the interacting waves demands an unnaturally large material birefringence or high-quality quasi-phasematched (QPM) devices with sub-µm periods. READ MORE
