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.

We establish the quantum theory of the one-mode micromaser injected by ultracold V-type three-level atoms with atomic coherence, and discuss the properties of the emission probability, the photon statistics, the spectrum and the velocity selection. We find the following results. There are two sets of peaks in the plot of the emission probability versus the cavity length. The injected atomic coherence can deeply affect the values of the two sets of peaks and the unresonant platform.

第一部分包括第一章到第四章，在这部分，我们建立了具有原子相干性的超冷V型三能级原子注入的单模Micromaser的量子理论，研究了原子发射几率、腔场光子统计、腔场光谱、以及腔对原子速度选择等性质，并着重研究了原子相干性对这些性质的影响。

Only an arbitrary single pulse among pulse train with temporal separation of about 1 ps was trapped by soliton pulse,the trapped pulse was blue-shifted and the optical spectra of trapped pulse was distinctly separated from those of the untrapped signal pulses.The trapped pulse can be easily picked off using a wavelength filter such as a fiber Bragg grating.

通过数值求解光子晶体光纤中脉冲传播满足的耦合非线性薛定谔方程，发现用孤子脉冲可俘获信号脉冲串中的任何一个脉冲，被俘获的信号脉冲的中心波长明显蓝移，在频域上和其他信号脉冲分离开来，于是让信号脉冲串在输出端通过布喇格光纤光栅，被俘获的信号脉冲将被过滤掉。

In 1966 Kenneth Greisen, Vadim Kuzmin and Georgiy Zatsepin showed that high-energy charged particles (cosmic rays are mostly atomic nuclei, and thus positively charged) should be slowed by collisions with the photons of the cosmic microwave background (radiation left over from the Big Bang that permeates all space).

1966年，肯尼思·格雷森、瓦迪姆·库兹民与乔奇·扎采品表示，充有高能量的粒子（大多数太空射线都属于原子核，因此也就具有正电）应该会由于太空微波背景下（渗透到整个宇宙的大碰撞所遗留下的辐射）的光子碰撞而减慢速度。
