Gap Solitons and Spin-Dependent Polarization Modulation in Resonant Photonic Bandgap Structures

本课题主要研究共振光子带隙(RPBG)结构中共振带隙孤子的形成问题，到目前为止，这方面的研究还只停留在理论上。在线性区域，谐振光脉冲被有效地从RPBG结构反射。在非线性区域，预测了光脉冲作为自感应透明带隙孤子无损耗地通过RPBG结构传输，或者被该结构俘获。持续时间为数百飞秒、皮秒或甚至纳秒(取决于两能级系统的特性)的单个光脉冲可以在RPBG结构中自陷并存储为相干偏振态。更广泛的影响涉及研究生和本科生的教育以及在光交换方面的应用。

This research project focuses on the formation of resonant gap solitons in a Resonant Photonic BandGap (RPBG) structure, which until now have only been explored in theory. In the linear regime, resonant optical pulses are efficiently reflected from RPBG structures. In the nonlinear regime, it has been predicted that an optical pulse propagates through the RPBG structure as a self-induced-transparency gap soliton without loss, or is trapped by the structure. A single optical pulse with duration of hundreds of femtoseconds, picoseconds, or even nanoseconds (depending on the characteristics of the two-level system) can be self-trapped in a RPBG structure and stored as a coherent polarization state. The broader impact involves education of both graduate and undergraduate students as well as applications in optical switching.
