Growth and Application of Chalcogenides of Lead and Related Compounds

Large grain, low-dislocation, high-quality single crystals of various Pb-salt compounds have been grownreproducibly by the Horizontal Unseeded Vapor Growth (HUVG) technique. The Tunable Diode Lasers withbetter performance have been made with such crystals. The annealing feature, dislocations and diffusion in thecrystals have also been investigated.

竖直液相外延炉生长Pb_(1-x)Sn_xTe/PbTe_(1-y)Se_y晶格匹配异质结激光器

本文根据Vagard定律,得到了Pb_(1-x)Sn_xTe/PbTe_(1-y)Se_y异质结晶格匹配条件,设计了生长参数,首次采用竖直液相外延炉生长了Pb_(1-x)Sn_xTe/PbTe_(1-y)Se_y品格匹配异质结,并制成了二极管激光器。     

2.1μ脉冲运转的GaInAs/AlGaAsSb DH激光器

近年发展起来的氟化物玻璃光纤是一种用于光通讯的新型光缆,其损耗比石英光纤低1—2个数量级,而最低损耗波长在2—4μm之间,因此研究在这个波段范围内工作的发射和接收器件是很有意义的,与Gasb晶格
