Abstract:
We provide methods and apparatus for preparing crystalline-clad and crystalline core optical fibers with minimal or no breakage by minimizing the influence of thermal stress during a liquid phase epitaxy (LPE) process as well as the fiber with precisely controlled number of modes propagated in the crystalline cladding and crystalline core fiber via precisely controlling the diameter of crystalline fiber core with under-saturated LPE flux. The resulting crystalline cladding and crystalline core optical fibers are also reported.

Claim (Index 18):
The crystalline cladding and crystalline core fiber of  claim 16 , wherein the core and/or cladding material is selected from the group consisting of pure and/or doped yttrium lithium fluoride (YLF), pure and/or doped yttrium orthovanadate (YVO4), pure and/or doped gadolinium orthovanadate (GdVO4), pure and/or doped colquiriite (LiSaF), pure and/or doped alumina (Al2O3), pure and/or doped spinel (MgAl2O4), pure and/or doped aluminum oxynitride (AlON), pure and/or doped yttria (Y2O3), pure and/or doped zirconia (ZrO2), pure and/or doped aluminum nitride (AlN), pure and doped yttrium iron garnet (YIG), pure and/or doped potassium tantalate niobate (KTN), pure and/or doped lithium niobate (LiNbO3), pure and/or doped tantalate niobate (LiTaO3), pure and/or doped lanthanum lead zirconate-titanate (PLZT), and pure and/or doped lead magnesium niobate-lead titanate (PMN-PT).
