摘要

这项研究描述了飞秒激光写入波导定向耦合器中与偏振相关的分光比。一般来说，输入光的不同偏振态存在不同的耦合强度。但是，如果输入光的线性偏振态与系统的一个对称轴不对齐，那么在不同相互作用长度的定向耦合器中，光的传输会受到额外的振幅跳动影响。我们提出了平面内和平面外定向耦合器的结果，并得到了理论分析的支持。这些新结果为理解和控制定向耦合器和更大光子电路的偏振特性提供了启示。

Polarization based modulation of splitting ratio in femtosecond laser direct written directional couplers

This work characterizes a polarization dependent splitting ratio in femtosecond laser written waveguide directional couplers. In general, different coupling strengths exist for different polarization states of the input light. However, if the linear polarization state of the input light is not aligned with one of the symmetry axes of the system, an additional amplitude beating is imposed on the transfer of light in directional couplers of different interaction length. We present results for in-plane and out of plane directional couplers, which are supported by theoretical analysis. These new results provide insights for understanding and controlling polarization properties of directional couplers and larger photonic circuits.

期刊介绍： Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
