Abstract
Abstract 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 LiIO 3 in a saturated solution of LiIO 3 in water. After the core is embedded a sufficient distance into the crystal the force is removed.
