A process of fabricating a hybrid single crystal fiber having nonlinear optical properties such as frequency doubling. Said process includes applying a force to a fiber core resting upon a bulk nonlinear crystal such as LiIo3 in a saturated solution of LiIO3 in water. After the core is embedded a sufficient distance into the crystal the force is removed. This invention relates generally to glass fiber optics, and particularly, relates to a process of fabricating fibers useful in nonlinear optics applications. The instant invention set forth a process of fabricating hybrid single crystal optical fibers having nonlinear optical properties therein and thereby overcome the problems set forth herein above. This process is distinct from the well known process of regulation. In the process of this invention, a fiber core is placed in direct contact with a bulk nonlinear crystal having an essentially flat surface thereon. The fiber core and bulk nonlinear crystal are immersed in a saturated solution where the equilibrium solid phase has the same composition as the bulk nonlinear crystal. Patents. jes
