摘要
用DMP450 型电子束镀膜机,制备了Y2O3ZrO2 膜,并将它用作1.3μm 半导体激光器的减反射膜.测试结果表明,镀膜后的半导体激光器其外微分子量效率明显提高,线性化也有改善.对于减反程度很高的管子,出现了超辐射现象.本文对这些现象及有关机理进行了讨论.
The Y\-2O\-3\|ZrO\-2 anti\|reflective(AR)coatings for 1 3μm laser diodes have been prepared with DMP\|450 electron beam evaprator.The external differential quantum efficiency of laser diode with coatings is larger than those without coatings,and the linearity of laser diodes output is improved.When the diode's back reflcetivity is reduced deeply,the diodes would have some properties of superluminescent diodes.All the phemomena and the mechanism are disussed in this paper.
