摘要
光存储技术由于能实现比其他信息存储技术更高的密度,受到各国重视.然而现行光存储技术的最高存储密度受到激光聚焦光斑最小尺寸限制.各国科学家竞相研究能突破这一限制.实现超高密度的下一代新技术.光子选通光谱烧孔就是其中的佼佼者.中国科学家在提高光子选通光谱烧孔工作温度方面做出了国际同行公认的贡献.光子选通光谱烧孔实际应用还有许多问题有待解决.
The highest storage density of the current optical information storage techniques is limited by the achievable size of focused laser spots. Scientists all over the world are trying to find techniques of optical information storage for next generation, which can provide a storage density several orders of magnitude higher than the present techniques. Spectral hole burning seems to be the most promising one. Chinese scientists have made significant contributions in raising spectral hole burning temperature, which is very important for application As far as we know, they are the first in the world to realize spectral hole burning at liquid nitrogen temperature.
