Abstract (AI)
A way to stabilize the domain structure in periodically poled Rb-doped KTiOPO4 samples at high-temperatures is presented. The domain contraction along the b-crystallographic axis that is observed when crystals are annealed at high temperatures is suppressed when the ends of the domains along the b-axis are diced away. Additionally, the thermal stability of self-assembled domain gratings with a sub-μm average periodicity of 650 ± 200 nm and a domain-width of 225 ± 75 nm in mm-thick samples is investigated, and it is shown that the key factor for the domain stability is the domain width rather than the interdomain distance.
Key Findings
1
A method is presented to stabilize periodically poled Rb-doped KTiOPO4 domain structures for high-temperature processes.
2
Cutting away the ends of domains along the b-axis suppresses domain contraction during high-temperature annealing in Rb-doped KTiOPO4.
3
Domain width, not interdomain distance, is identified as the key factor determining thermal stability of the domain gratings.
4
Self-assembled domain gratings in mm-thick Rb-doped KTiOPO4 have average periodicity 650 ± 200 nm and domain width 225 ± 75 nm.
