光谱特性

In order to obtain better characteristics of photonic crystal lasers, the wafer bonding technology is introduced to integrate MQWs wafer with different uncompatible wafers. We utilize the direct bonding method and glue bonding method to integrate the 1550nm long-wavelength MQWs with DBR wafer or sapphire. The effect factors of bonding process and choice of bonding materials are discussed. At last, we measure the photoluminescence spectra of our membrane devices and bonding samples.

为了得到更好的光谱特性，我们介绍了各种晶圆接合技术去整合含有多层量子井结构的晶圆与其不相容的材料，我们利用直接接合和溶胶接合的方法去接合1550nm长波长的多层量子井晶圆与含有DBR结构的晶圆或sapphire，并对於各种接合影响因素与材料的选择加以讨论，最后再对我们的层状光子晶体雷射和晶圆接合后的样本做量测。

X=0, 11, 22, 33, 44, and 55 borophosphate glasses series have investigated, and it is found that:(1) both the covalency bonding between Yb〓 ion and oxygen ion and the asymmetry in local structures surrounding Yb〓 ion have strong effects on integrated absorption cross section ∑〓 and emission cross section σ〓 of Yb〓 ion in borophosphate glasses;(2) the borophosphate glasses and borate glasses appear superior as Yb-gain media to the phosphate glasses, although the phosphate glasses have been demonstrated as the most appropriate Ndgain media.
