Fabrication of Y-splitters and Mach-Zehnder interferometers on (Yb, Nb):RbTiOPO4/ RbTiOPO4 epitaxial layers by reactive ion etching and on RbTiOPO4 by Cs+ diffusion
We present the fabrication and characterization of Y-splitters and Mach-Zehnder Interferometers by the two different techniques of reactive ion etching and ion exchange on (Yb,Nb):RbTiOPO4/ RbTiOPO4 and RbTiOPO4, respectively. Liquid phase epitaxy was used to grow planar thin films followed by reactive ion etching for fabrication of structures over it. Cs+ ions were used for diffusion process because they produce a significant increase in the refractive index and the ionic radius is close to the Rb+ radius. It has been found that these structures can guide light with TM polarization at 1520 nm.

Abstract

We present the fabrication and characterization of Y-splitters and Mach-Zehnder Interferometers by the two different techniques of reactive ion etching and ion exchange on (Yb,Nb):RbTiOPO4/ RbTiOPO4 and RbTiOPO4, respectively. Liquid phase epitaxy was used to grow planar thin films followed by reactive ion etching for fabrication of structures over it. Cs+ ions were used for diffusion process because they produce a significant increase in the refractive index and the ionic radius is close to the Rb+ radius. It has been found that these structures can guide light with TM polarization at 1520 nm.
