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.sub.3 in a saturated solution of LiIO.sub.3 in water. After the core is embedded a sufficient distance into the crystal the force is removed.
Claims6
A process of fabricating hybrid single crystal fibers, said process comprising the steps of:
- placing a bulk nonlinear crystal in a container for holding a solution, said bulk nonlinear crystal having a substantially flat upper surface;
- selectively placing at least one fiber core on said surface of said bulk nonlinear crystal;
- holding said fiber core upon said upper surface;
- placing a controlled force biasing means for bearing upon said fiber on top of said fiber core;
- filling said container with a saturated solution whose equilibrium solid phase matches the composition of said crystal, said solution covering said fiber core;
- applying said biasing means to said fiber core in a controlled manner;
- and
- releasing said biasing means after said fiber core is embedded a fixed distance into said bulk nonlinear crystal.
