Abstract

Rare earth ion doped potassium double tungstate gain materials have recently shown a great promise for the development of waveguide amplifiers and lasers exhibiting excellent performance. To enable the use of this material in larger nanophotonic platforms, sharp bends are required. In this work we study the effect of the anisotropy of potassium double tungstates on the bend losses of high contrast waveguides using three different simulation methods. It is concluded that the existence of this anisotropy has not detrimental effect on the bend losses, therefore opening the door to the utilization of this material for integrated nanophotonics.
