A Novel Route to Fibers with Incongruent and Volatile Crystalline Semiconductor Cores: GaAs
نویسندگان
چکیده
A novel extension to the molten core method was employed realize a glass-clad, crystalline gallium arsenide (GaAs) fiber for first time author’s knowledge. GaAs is of considerable interest its optoelectronic and nonlinear properties, but decomposition volatility, usually leading incongruent solidification, normally preclude melt-processing under ambient conditions into an optical fiber. Presented here are results on tin as flux melt at temperature where volatility negligible, permitting thermal drawing long lengths (100 m) GaAs-containing fibers. Laser annealing segregate Sn phases, both across along This work presents important new tool scalable fabrication glass-clad materials previously thought incompatible with processes opens door wide range useful in-fiber devices.

A novel method for the synthesis of a new class of thermotropic liquid crystalline polymers has been developed: it proceeds via a polyaddition reaction involving diepoxy-containing mesogene groups and a monoamine (aniline). The reaction between the epoxy ring and the primary amine produces an intermediate containing a secondary amine which undergoes further reaction with an epoxy ring of anothe...
