Theory of Solitons in Microresonators

本计画将发展一种新的理论，描述微共振器中频率梳的产生。由数千条等间距窄共振线组成的光频梳在20世纪90年代已经被证明，它们的发现彻底改变了频域和时域的精确测量，并使光学时钟的发展成为可能。梳子的研究已经在2005年获得了诺贝尔奖（T。Hänsch和J. Hall），并吸引了越来越多的关注与稳步增长的出版物，引文和应用。近年来，随着微谐振器技术的发展和微谐振器频率梳--微梳的发现和开发，微谐振器频率梳的研究取得了显著的进展。微梳正在成为一种颠覆性技术，用于在芯片级平台上实现精确计量，频率和波形合成以及信息的光学处理，这迫切需要全面的理论理解，构成本博士项目的主要课题。

This project will pursue development of a new theory describing frequency comb generation in microresonators. Optical frequency combs consisting of thousands of equally spaced narrow resonance lines have been demonstrated in the 1990s and their discovery has completely revolutionised precision measurements in frequency and time domains and enabled the development of optical clocks. The comb research was already awarded the Nobel Prize in 2005 (T. Hänsch and J. Hall) and is attracting an ever increasing attention with a steadily growing number of publications, citations and applications. In the past few years, this research field has witnessed an outstanding progress through the development of the microresonator technology and observation and exploitation of the microresonator frequency combs - microcombs. Microcombs are emerging as a disruptive technology for realizing precision metrology, frequency, and waveform synthesis and optical processing of information on a chipscale platform, which urgently requires a comprehensive theoretical understanding constituting a main topic of this PhD project.
