为了改进绝热微环谐腔型的结构、降低谐振腔腔体损耗，采用了基于绝热过渡曲线的设计方法，提出了新型载流子注入／抽取结构，进行了理论分析和实验验证，取得了绝热微环谐振腔的谐振峰线宽、消光比及频率响应参量数据，比较了其与传统微环谐振腔的损耗。结果表明，使用所设计的外半径为2μm的谐振腔的谐振峰线宽仅为普通微环谐振腔的29．5％，消光比为13．5dB，电阻电容限制带宽提高了4倍，10Gbit／s调制速率下能耗仅为5．1fJ／bit。这一结果大幅改善了绝热微环谐振腔的频率响应特性，降低了功耗。对腔形和载流子注入／抽取结构的研究可以进一步改善绝热微环谐振腔的性能，推动低能耗器件研究的发展。

For the purpose of improving the structure of adiabatic micro-ring resonator and reducing the resonator cavity loss, a new carrier injection/extraction structure was proposed based on adiabatic transition curve .After theoretical analysis and experimental verification , the data of resonant full wave at half maximum ( FWHM ) of the adiabatic micro-ring resonator , extinction ratio and frequency response parameters were obtained and compared with the loss of a traditional micro -ring resonator . The results show that FWHM of the adiabatic ring with outer radius of 2μm is only 29.5%of that of a traditional micro-ring, the constrained bandwidth of resistance and capacitance increases 4 times, extinction ratio is 13.5dB and energy consumption is 5.1fJ/bit under modulation speed of 10Gbit/s.This research is helpful to improve the frequency response and reduce the power consumption of an adiabatic micro-ring resonator significantly .The study on adiabatic transition and carrier injection/extraction structure can further improve the performance of the adiabatic micro-ring, and push the development of low energy consumption research.
