class="relatedlink">电子</a>器件有了更深入的了解，虽然之前也从课本上或其他方面了解了一些概念和具体实物，但是上完这门课，才知道自己之前并未真正了解它，一学期的学习虽然没能把老师教授的学全，但是也学到了不少有用的知识。<br /> 下面我将总结自己一学期收获的内容。<br /> 所谓光电子器件，广义上讲指通过以光电互相转换为主要形式的光效应完成信息或能量转换的功能型器件。它是光学与光电子学与其应用之间以及其他学科之间联系的重要纽带。光电子器件种类有很多。 <br /> <a href="http://sensor.oecr.com" target="_blank" class="relatedlink">半导体</a><a href="http://laser.oecr.com" target="_blank" class="relatedlink">激光</a>器：以半导体<a href="http://material.oecr.com" target="_blank" class="relatedlink">材料</a>为工作物质来产生激光的器件，又称半导体激光二极管，是实用中最重要的一类激光器。优点：体积小、效率高、寿命长。半导体激光器一般可分为同质结、单异质结、双异质结等几种。半导体激光器工作原理是激励方式，利用半导体物质（即利用电子）在能带间跃迁<a href="http://light.oecr.com" target="_blank" class="relatedlink">发光</a>，用半导体<a href="http://material.oecr.com" target="_blank" class="relatedlink">晶体</a>的解理面形成两个平行反射镜面作为反射镜，组成谐振腔，使光振荡、反馈、产生光的辐射放大，输出激光。半导体二极管激光器在激光<a href="http://ofc.oecr.com" target="_blank" class="relatedlink">通信</a>、光存储、光陀螺、激光打印、测距以及雷达等方面以及获得了广泛的应用。目前，半导体激光器已成为激光产业的主要主城部分，成为各国发展信息、通信、家电产业及军事装备不可或缺的重要基础器件，我们未来半导体激光器的潜力将被将被充分发掘出来，并得到更广泛的应用。<br /> <a href="http://solar.oecr.com" target="_blank" class="relatedlink">太阳能</a>电池;通过光电效应或者光化学效应直接把光能转换成电能的装置，总所周知，太阳蕴含着无穷无尽的能量，能够利用好这些能量，必将解决人类的能源问题，而太阳能电池则是利用太阳能的最重要途径。最为一个人口大国，中国的能源问题一直是头疼的问题，如果能够赶上太阳能技术发展的潮流，必将为国人造福。中国对太阳能电池的开发研究工作高度重视，中国已成为全球<a href="http://solar.oecr.com" target="_blank" class="relatedlink">光伏</a><a href="http://b.oecr.com/sell" target="_blank" class="relatedlink">产品</a>最大制造国。目前，太阳能电池的应用已从军事领域、航天等进入工农业、通信家电、以及基础设施，但是成本过高仍是其大规模使用的障碍。但是从长远来看，随着太阳能电池制造技术以及新的光电转换装置的发明，各国对环境的保护和可再生能源的巨大需求，太阳能电池将是利用太阳辐射能比较切实可行的方法，可为人类未来大规模利用太阳能开辟广阔的前景<br /> 详情请查看网站eulike.com，<br /> 相信伴随着技术的进步，一系列的困难将被克服，电池效率的提高，太阳能将更好地为人类造福。<br /> 液晶一种高分子材料，因为其特殊的<a href="http://theory.oecr.com" target="_blank" class="relatedlink">物理</a>化学光学特性，20世纪中叶开始被广发应用在轻薄型的<a href="http://display.oecr.com" target="_blank" class="relatedlink">显示</a>技术上。液晶其实很常见，比如我们手上带的电子表和和所使用的计算器的显示板，或者家里的液晶电视。利用液晶的电光效应把电信号转换成字符、图像等可见信号，液晶种类很多，通常按液晶分子的中心桥键和环的特征进行分类，目前已合成一万多种液晶材料，其中常用的有上千种。液晶显示材料具有明显的优点：驱动电压低、能耗小、可靠性高、显示信息量大、对人体无危害、便于携带。由于这些优点液晶材料制成的计算机终端黑胆石可以大幅度减小体积。液晶显示技术对显示显像产品结构产生了深刻影响，促进了微电子技术和光电信息技术的发展。<br /> 其实我觉得自己了解还不可全面，还仅停留在表层，还有很多光电子器件还未熟悉和了解，我相信自己在今后会不断完善在这一方面的知识，并能有所建树。</td></tr></table> <div class="ptg mbm mtn"> <a title="工作原理" href="misc.php?mod=tag&id=1013" target="_blank">工作原理</a>, <a
