Developing Zinc-Indiffused Periodically Poled Lithium Niobate Ridge Waveguides for Quantum Applications at Visible Wavelengths

Tailored laser sources at visible range wavelengths are in ever increasing demand as technologies for quantum computing, sensing, and remote imaging continue to evolve. As these technologies start to move out of the labora-tory and into the field, the requirement for compact, efficient, rugged laser sources makes wavelength conversion of established laser systems and diodes an obvious choice.
